Question

A biologist models the size of a population of songbirds over time,t, in years, with this function.

f(t)=312(0.97)^t. which statements about the population are supported by this function

Answer 1

B, E

Explanation:

Exponential growth or decay:

f(t) = A(1 + r)^t

A is the initial number.

r is the rate of change.

In this case,

1 + r = 0.97,

so r = -0.03 = -3%

The population is decreasing at a rate of 3%

Answer: B, E
