Question

2 incorrect
select the correct answer.
the graph shows the population of black toads in a forest reserve since their introduction. it also includes functions drawn by different researchers to estimate the change in population of the toads.
which function best models the researchers’ data?
black toad population
graph with x-axis labeled years since introduction (0 to 10), y-axis labeled black toads (thousands) (0 to 16). data points and four functions (a, b, c, d) are plotted.
a. function a
b. function b
x c. function c
d. function d

Explanation:

Step1: Analyze Data Points

The data points (black dots) represent the actual population of black toads. We need to find which function (curve) passes closest to these points.

Step2: Compare Curves

• Function A: The curve is too low, not close to most data points.
• Function B: Also relatively low, not matching the spread of data.
• Function C: Doesn't align well with the points, especially at later years.
• Function D: The curve (yellow) appears to be the closest to the majority of the data points, fitting the trend of the population change.

Answer:

D. function D
