Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.

Question

y=8200(0.96)^x

Thats the exponential function.

Answer 1

Depends; is "x" rising or declining?

Answer 2

y = 8200(0.96)^x

Since 0.96 < 1, the function is an exponential decay function.

The function can also be written as 8200(1 - 0.04)^x.

The rate of decrease is 4% (that's 0.04 expressed as a percent)
