Question

Given the exponential function f(x) = 16(0.75)x, classify the function as exponential growth or decay and determine the percent rate of growth or decay.

Exponential growth, 75% increase
Exponential decay, 75% decrease
Exponential growth, 25% increase
Exponential decay, 25% decrease

Answer 1

Answer:

exponential growth 75% decrease

Step-by-step explanation:

Answer 2

Answer:

So the rate of decay is 0.25, or 25%.

Step-by-step explanation:

The variable r gives the rate of decay in the formula f(x) = P(1 − r)x = 16(1 − 0.25)x.
