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

A (x) = 680 ∙ 4.3x

a=680, b=4.3

Step-by-step 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

Step-by-step 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
