To determine whether the function representing the number of math problems Jana completed is linear or non-linear, we can analyze the data provided in the table:
Minutes | Math Problems Completed
---------------------------
1 | 3
2 | 7
3 | 14
4 | 15
5 | 19
To check if the function is linear, we need to see if there is a constant rate of change (slope) in the number of math problems completed as the minutes increase.
We can calculate the differences in math problems completed for consecutive minutes:
- From 1 to 2 minutes: 7 - 3 = 4
- From 2 to 3 minutes: 14 - 7 = 7
- From 3 to 4 minutes: 15 - 14 = 1
- From 4 to 5 minutes: 19 - 15 = 4
The differences between the counts of math problems completed are not constant (4, 7, 1, 4).
Since the rate of change is not constant, this indicates that the function is non-linear.
Thus, we can conclude: This represents a non-linear function because the rate of change in math problems completed is not constant.
