Question

Identify the initial amount a and the growth factor b in the exponential function.

A(x) = 680 ∙ 4.3x

Answer 1

a=680, b=4.3

Explanation:

The initial amount, a, is the value of A(x) when x=0. It is A(0)=680 ∙ 4.3^0

a=680

The growth factor, b, in the exponential function is its base, A(x) = 680 ∙ 4.3^x

b=4.3

Answer 2

Explanation:

given A(x) = 680 ∙ 4.3x

the general form for exponential function is A(x)=ab^x, where a is the initial amount and b is the growth factor

so a=680 n b=4.3
