Question

the function is exponential growth when b > 1. using r to represent growth rate as a decimal, b = 1 + r. so, an exponential growth function can. what does the “r” mean in the rule b = 1 + r? multiple - choice question

Explanation:

Step1: Recall exponential - growth formula

The general form of an exponential - growth function is $y = a\cdot b^{x}$, where $b>1$ represents the growth factor. When we express the growth rate $r$ (as a decimal) in terms of the growth factor $b$, the formula is $b = 1 + r$. Since it is an exponential growth function, $b>1$.

Answer:

The function is exponential growth when $b>1$. Using $r$ to represent growth rate as a decimal, $b = 1 + r$.
