Question

Identify the initial amount a and the growth factor b In the exponential function f(x)=620•7.8x

A 620, 7.8
B 7.8, 620
C 7.8x, 620
D 620, 7.8x

Answer 1

620, 7.8^x

Explanation:

Answer 2

Given:

f(x) = 620e^7.8x

The standard equation for an exponential function is f(x) = Aoe^bx

where Ao is the initial amount
b is the growth factor

so, in this case, the initial amount is 620 and the growth factor is 7.8
