Practice Flashcards: PSAT Advanced Math — growth that multiplies rather than adds | Zestly

Question 1

Exponential growth base

Accepted Answer

The base $b$ is $1 + r$, where $r$ is the growth rate as a decimal.

Question 2

Exponential decay base

Accepted Answer

The base $b$ is $1 - r$, where $r$ is the decay rate as a decimal.

Question 3

General exponential model

Accepted Answer

$A = P(b)^t$, where $P$ is the initial value, $b$ is the factor, and $t$ is time.
