Question

7.

The table shows the estimated number of deer living in a forest over a five-year period. Are the data best represented by a linear, exponential, or quadratic model? Write an equation to model the data.
Year
Estimated Population

0 91
1 70
2 54
3 42
4 32

A. quadratic; 0.77x2 + 91
B. exponential; y= 91 * 0.77x
C. linear; y= 0.77x + 91
D. quadratic; y= 91x2 + 0.77

Answer 1

All I can say is that it isn't linear, as the number would then be the same every year

Answer 2

B. exponential; y= 91 * 0.77x

Explanation:

The Answer is A.

y=91*0.77^x

I just substituted the x on all of them and only one got the corrct y which is A.
