Question

Decide whether the function is an exponential growth or exponential decay function and find the constant percentage rate of growth or decay. f(x) = 2500 ⋅ 0.9968^x

Answer 1

Exponential decay function; -0.32%

Step-by-step explanation:

y = a(b)^x

0.9968 (b) is less than 1 so it is decay.

1 - 0.9968 = 0.0032 and to convert that to percent you multiply it by 100 so it becomes -0.32%

It is negative because it is a decay
