Explanation of Solution

Given information : the function is f=|x|

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 2.5, Problem 58E

Form the above graph it is observed that the graph of the function of g is the graph of f=|x| stretched vertically by a factor of 2 .

Use the definition of vertically stretching of graphs,

Then for the function of g , multiply the function f=|x| by 2 .

Hence, the function g=2|x| .
