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.

This is the table:

Year Estimated Population

0 98

1 77

2 61

3 48

4 38

A. Quadratic; y=0.79x^2 + 98

B. Exponential; y=98 * 0.79^x

C. Quadratic; y=98x^2 + 0.79

D. Linear; y=0.79x+98

Fields · Answer 1

All the functions grow with x except B that decreases when x grows. That i your function. Also check that when you divide the population of two consecutive years, the ratio remains 0.79 approx

The solution is B
