Eliza Ross · Answer 1

growth 800%

Step-by-step explanation:

y=4 (9) ^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

9-1 = 8

Change to a percent

800%

Kara Hebert · Answer 2

Growth, 800%

Step-by-step explanation:

9 > 1

So growth

9 (4¹) = 36

(36-4) / 4 * 100

= 800%

Determine whether the function is growth or decay AND its percentage of growth or decay.y=4 (9) ^x
