Question

What is the a, b, and r for y=3.6(1.25)^x

Answer 1

a=3.6, v=1.25 and r=25%

Explanation:

The given exponential function is

`y = 3.6 {(1.25)}^(x)`

We compare to the form:

`y = a{(b)}^(x)`

We have a=3.6, b=1.25

The r is the percentage of increase or decrease.

We realized there is a 25% increase because

`y = 3.6 {(1 + 25\%)}^(x)`

Hence

`r = 25\%`
