Decide whether the function is an exponential growth or exponential decay function and find the constant percentage
rate of growth or decay.
-$$f ( x ) = 99 \cdot 0.03 ^ { x }$$
A) Exponential growth function; $3 \%$
B) Exponential decay function; $- 97 \%$
C) Exponential decay function; $- 0.97 \%$
D) Exponential decay function; 3\%

Question

Quizplus · Accepted Answer

The function is an exponential decay because the base of the exponent, 0.03, is between 0 and 1. The constant percentage rate of decay is 100% - 3% = 97%, hence -97%.

Decide Whether the Function Is an Exponential Growth or Exponential f(x)=99⋅0.03xf ( x ) = 99 \cdot 0.03 ^ { x }f(x)=99⋅0.03x
