Question

Which is a stretch of an exponential decay function? f(x) = one-fifth (one-fifth) superscript x f(x) = one-fifth(5)x f(x) = 5one-fifth f(x) = 5(5)x

Answer 1

The exponential function that represents a stretch of a decay function is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$

What is an exponential function?

An exponential function is modeled by:

$y = ab^x$.

In which:

• a is the initial value.

• b is the rate of change.

It represents a stretch if a > 1, and a decay function if b < 1. Researching the problem on the internet, the correct option is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$
