Question

Which is a stretch of an exponential decay function ?

Answer 1

Using translation concepts, a stretch of a decay exponential function is given by:

$f(x) = 5\left(\frac{1}{5}\right)^x$

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

An exponential decay function is given by:

$y = ab^x$

In which |b| < 1.

A stretch means that the function is multiplied by a factor with absolute value greater than 1, hence the function would be given by:

$f(x) = 5\left(\frac{1}{5}\right)^x$
