Question

The exponential function f(x)=78(1.3)^x Model exponential (growth or decay). What is the rate of growth or decay?

Answer 1

Answer:

Growth, rate: 30%

Step-by-step explanation:

Since 1.3 > 1,

It's growth

(1.3 - 1) × 100

= 30%

Answer 2

Answer:

growth 30%

Step-by-step explanation:

This is in the form

y =a b^x

Where b is the growth rate

b>1 it is growth

b<1 it is decay

1.3 >1 so it is growth

b-1 = .3 so the growth rate is .3 = 30%
