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:

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%

Growth, 300%

Step-by-step explanation:

4 > 1

so Growth

(4 - 1) * 100 = 300%
