Identify the initial value in each formula below, and state whether the formula models exponential growth or
exponential decay. justify your responses.
e. f(t) = 3 / 2 (2 / 3)^t

Initial value 3/2

Exponential decay

Step-by-step explanation:

Exponential decay has the following formula:

f(t) = a(1-r)^t

where

a = initial value

r = rate of decrease

t = time

If the value inside of the parenthesis is less than 1, then the formula models exponential decay.

If the value inside of the parenthesis is more than 1, then the formula models exponential growth.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
