Question

If you vertically stretch the exponential function f(x) = 2* by a factor of 5, what

is the equation of the new function?

Answer 1

f(x)=5(2^x)

Explanation:

We have been given the parent function

We have the transformation rule:

Rule: If the parent function y =f(x) is stretched vertically by a factor 'k' then the equation becomes y=kf(x).

Here, the exponential function vertically stretched by a factor 5, hence, k = 5.
