The function in the table below shows the relationship between the total number of houses built in an area and the number of months that passed.
A two column table with five rows. The first column, Months Passed, has the entries, 0, 3, 4, 8. The second column, Total Houses Built, has the entries 0, 33, 46, 108.
Which best describes the data set?
It is nonlinear because the “Total Houses Built” column does not increase at a constant additive rate.
It is nonlinear because the “Months Passed” column does not increase at a constant additive rate.
It is nonlinear because the increase in the “Total Houses Built” compared to the increase in the “Months Passed” does not show a constant rate of change.
It is linear because the increase in the “Total Houses Built” compared to the increase in the “Months Passed” shows a constant rate of change

To determine whether the data set is linear or nonlinear, we need to examine the changes in the "Total Houses Built" with respect to changes in the "Months Passed."
Let's break down the data:
- From month 0 to month 3:
- Houses built = 33 - 0 = 33
- Months passed = 3 - 0 = 3
- Rate of change = 33 houses / 3 months = 11 houses per month
- From month 3 to month 4:
- Houses built = 46 - 33 = 13
- Months passed = 4 - 3 = 1
- Rate of change = 13 houses / 1 month = 13 houses per month
- From month 4 to month 8:
- Houses built = 108 - 46 = 62
- Months passed = 8 - 4 = 4
- Rate of change = 62 houses / 4 months = 15.5 houses per month
Now we can summarize the rates of change:
- From 0 to 3 months: 11 houses per month
- From 3 to 4 months: 13 houses per month
- From 4 to 8 months: 15.5 houses per month
Since the rates of change are not constant (11, 13, and 15.5), this indicates that the relationship is not linear.
Therefore, the correct statement that best describes the data set is:
**It is nonlinear because the increase in the “Total Houses Built” compared to the increase in the “Months Passed” does not show a constant rate of change.**
Let's break down the data:
- From month 0 to month 3:
- Houses built = 33 - 0 = 33
- Months passed = 3 - 0 = 3
- Rate of change = 33 houses / 3 months = 11 houses per month
- From month 3 to month 4:
- Houses built = 46 - 33 = 13
- Months passed = 4 - 3 = 1
- Rate of change = 13 houses / 1 month = 13 houses per month
- From month 4 to month 8:
- Houses built = 108 - 46 = 62
- Months passed = 8 - 4 = 4
- Rate of change = 62 houses / 4 months = 15.5 houses per month
Now we can summarize the rates of change:
- From 0 to 3 months: 11 houses per month
- From 3 to 4 months: 13 houses per month
- From 4 to 8 months: 15.5 houses per month
Since the rates of change are not constant (11, 13, and 15.5), this indicates that the relationship is not linear.
Therefore, the correct statement that best describes the data set is:
**It is nonlinear because the increase in the “Total Houses Built” compared to the increase in the “Months Passed” does not show a constant rate of change.**

To determine who had a head start and how large it was, we need to compare Nina's distance to Ryan's distance at the same time intervals.
### Nina's Distance (from the first set) at Time in Seconds:
- At 4 seconds: 32 meters
- At 6 seconds: 48 meters
- At 8 seconds: 64 meters
- At 10 seconds: 80 meters
### Ryan's Distance (from the table):
- At 4 seconds: 35 meters
- At 6 seconds: 47.5 meters
- At 8 seconds: 60 meters
### Comparison at 4 seconds:
- Nina: 32 meters
- Ryan: 35 meters
At 4 seconds, Ryan is ahead with 35 meters while Nina has only run 32 meters. Ryan is ahead by:
- Head start = Ryan's distance - Nina's distance = 35 - 32 = **3 meters**.
### Comparison at 6 seconds:
- Nina: 48 meters
- Ryan: 47.5 meters
At 6 seconds, Nina exceeded Ryan's distance by:
- Head start = Nina's distance - Ryan's distance = 48 - 47.5 = **0.5 meters**.
### Comparison at 8 seconds:
- Nina: 64 meters
- Ryan: 60 meters
At 8 seconds, Nina is ahead:
- Head start = Nina's distance - Ryan's distance = 64 - 60 = **4 meters**.
### Conclusion
Initially, Ryan had a head start of **3 meters** because he was ahead of Nina at 4 seconds. As the race progressed, Nina eventually surpassed Ryan after that point.
So, the final answer:
**Ryan** had a head start of **3 meters**.
### Nina's Distance (from the first set) at Time in Seconds:

At 4 seconds, Ryan is ahead with 35 meters while Nina has only run 32 meters. Ryan is ahead by:
- Head start = Ryan's distance - Nina's distance = 35 - 32 = **3 meters**.
### Comparison at 6 seconds:
- Nina: 48 meters
- Ryan: 47.5 meters
At 6 seconds, Nina exceeded Ryan's distance by:
- Head start = Nina's distance - Ryan's distance = 48 - 47.5 = **0.5 meters**.

A linear function and a nonlinear function differ fundamentally in their rate of change, behavior, and representation.
### Linear Function
#### Definition:
A linear function is a function whose graph is a straight line. It can be expressed in the standard form \(y = mx + b\), where:
- \(m\) is the slope (rate of change).
- \(b\) is the y-intercept (the value of \(y\) when \(x = 0\)).
#### Characteristics:
- The rate of change (slope) between any two points is constant.
- The equation of a linear function represents a proportional relationship among the variables.
#### Table Representation:
In a table representing a linear function, if you observe the values for \(y\) as \(x\) changes, the differences between successive \(y\) values will remain consistent.
| \(x\) | \(y\) |
|-------|-------|
| 0 | 2 |
| 1 | 4 |
| 2 | 6 |
| 3 | 8 |
| 4 | 10 |
In this table:
- The difference in \(y\) (output) is constant as \(x\) (input) increases.
#### Graph Representation:
The graph of a linear function is a straight line. Each point on the line represents a solution to the equation of the function.
### Nonlinear Function
#### Definition:
A nonlinear function is one in which the relationship between the independent variable and the dependent variable is not a straight line. It can take various forms, such as quadratic, exponential, or logarithmic functions.
#### Characteristics:
- The rate of change is not constant; it can accelerate or decelerate.
- The equation may not be expressible in the linear format \(y = mx + b\).
#### Table Representation:
In a table for a nonlinear function, the differences between successive \(y\) values may change.
| \(x\) | \(y\) |
|-------|-------|
| 0 | 1 |
| 1 | 2 |
| 2 | 4 |
| 3 | 9 |
| 4 | 16 |
Here, you can see that the differences in \(y\) values (1, 2, 5, 7) are not constant, indicating a nonlinear relationship.
#### Graph Representation:
The graph of a nonlinear function might be a curve, such as a parabola or an exponential curve.
In summary:
- **Linear functions** produce straight lines with constant rates of change, and their tables show consistent differences in \(y\).
- **Nonlinear functions** produce curves and have variable rates of change, with their tables showing varying differences in \(y\) values as \(x\) changes.

A linear function is a function whose graph is a straight line. It can be expressed in the standard form \(y = mx + b\), where:
