Determine whether the function is growth or decay AND its percentage of growth or decay.

1. y= .3(4)^x

Growth , 300%

Step-by-step explanation:

4 > 1

so Growth

(4 - 1) × 100 = 300%

growth, 300%

Step-by-step explanation:

y=.3(.4)^x

The equation is of the form

y =a b^x

b tells us growth or decay

b>1 growth

b<1 decay

This is growth

To find the percent growth take b-1

4-1 = 3

Change this to percent

300%

c is the correct answer
