Question

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?

Explanation:

The scatter plot data points follow a curved (parabolic-like) trend that first decreases, reaches a minimum, then increases. Function C passes closest to all the plotted data points, matching the overall trend of the toad population's change over time better than the other functions (A dips too low, B is below most points, D is above most points).

Answer:

C
