Question

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

Answer 1

Answer:

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

Step-by-step 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

$r = 25\%$
