Question

Given the following exponential function, identify whether the change representsgrowth or decay, and determine the percentage rate of increase or decrease.y = 70(0.96)Growth ____% increase

Answer 1

$y=70(0.96)^x$

Given that the base of the exponential function, 0.96, is less than 1, then the change represents a decay.

The percentage rate of decrease is 1 - 0.96 = 0.04 or 4%
