Question

A certain population of beetles is increasing at a rate of 22% per month if they are currently if there are currently 350 Beatles the equation f of x = 350 * 1.22x can be used to model the situation finish the chart and plot the points to determine which graph correctly displays the situation

To model the beetle population with the equation \( f(x) = 350 \times 1.22^x \), where \( x \) is the number of months and \( f(x) \) is the population at that time, we can calculate the population for a series of months.

Here is a chart for the population over the first few months:

| Month (x) | Population (f(x)) |
|-----------|----------------------------|
| 0 | \( 350 \times 1.22^0 = 350 \) |
| 1 | \( 350 \times 1.22^1 \approx 427 \) |
| 2 | \( 350 \times 1.22^2 \approx 520 \) |
| 3 | \( 350 \times 1.22^3 \approx 635 \) |
| 4 | \( 350 \times 1.22^4 \approx 774 \) |
| 5 | \( 350 \times 1.22^5 \approx 946 \) |

Now we compute each population value:

1. For \( x = 0 \):
\[
f(0) = 350 \times 1.22^0 = 350
\]

2. For \( x = 1 \):
\[
f(1) = 350 \times 1.22^1 \approx 350 \times 1.22 = 427
\]

3. For \( x = 2 \):
\[
f(2) = 350 \times 1.22^2 \approx 350 \times 1.4884 \approx 520
\]

4. For \( x = 3 \):
\[
f(3) = 350 \times 1.22^3 \approx 350 \times 1.8158 \approx 635
\]

5. For \( x = 4 \):
\[
f(4) = 350 \times 1.22^4 \approx 350 \times 2.2196 \approx 774
\]

6. For \( x = 5 \):
\[
f(5) = 350 \times 1.22^5 \approx 350 \times 2.8490 \approx 996
\]

Now, plotting these points on a graph:

- (0, 350)
- (1, 427)
- (2, 520)
- (3, 635)
- (4, 774)
- (5, 946)

To determine which graph correctly displays this situation, look for a graph that shows an exponential increase starting from the point (0, 350) and rising steeply as \( x \) increases. The growth rate should show a consistent upward curve indicating rapid growth due to the 22% increase per month.

When you have the options, select the graph that matches this exponential growth pattern!
