Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=47(0.63)
x

decay function

percent rate of decrease is 37%

Step-by-step explanation:

I assume the x is the exponent.

The number raised to the exponent x is 0.63 which is between 0 and 1. That means that as x increases, (0.63)^x decreases. That means it is an exponential decay function.

Each unit more in x results in 0.63 being multiplied by the number.

Since 1 - 0.63 = 0.37, the percent rate of decrease is 37%.

decay function

percent rate of decrease is 37%
