Question

Given the function y=(0.84)t, determine whether the function represents growth or decay and identify the rate of change

Answer 1

This function is a decay function and the rate of change is 0.16.

Explanation:

We can tell this a decay function because the number in the parentheses is less than 1.

The "parent" function of a decay function is
`y = (1-b)^(x)`, where x represents the t and b is the rate of change.

So that means 0.16 is b and 1 - 0.16 resulted in 0.84.
