Question

Plz, help!!! And hurry!!!

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=430(1.275)^x

Answer 1

First, you remove the parenthesis. Therefore, you'll have y = 430 ⋅ 1.275^x. Then graph it. It's Increasing.

Answer 2

It's growth, because the number to which "x" is the exponent is 1.275, which is greater than 0.

Because that number is 1.275, the graph's percentage rate increase is +27.5%
