Question

Let f(x) = |x|, where x can be any real number. Write a formula for the function whose graph is the

transformation of the graph of f given by the instructions below.
c. A vertical scaling (a vertical stretch) with scale factor of 5

Answer 1

y = 5f(x)

Please see the picture below

Explanation:

Given the function f(x) = |x|, to transform the function y=f(x) with a vertical scaling with scale factor of 5, you should multiply the function by 5 to obtain the result;

y = 5f(x)
