Determine if its a growth or decay.Then find the percent increase of decrease.
1.y=16(.25)^x
Decrease because higher powers of 0.25 are smaller than 0.25
-----------------------------
2.y=0.8(1.28)^x
Increase because higher powers of 1.28 are bigger than 1.28
-----------------------------
3.y=17(1/5)^x
Decrease because higher powers of (1/5) are smaller than 1/5.
