Solutions

Chapter 2.5, Problem 17E

a.

To determine

To describe how the graph of the function can be obtained from the graph of y=|x| .

Expert Solution

Answer to Problem 17E

The graph of g(x)=|x+2|2 is obtained by shifting the graph of f(x)=x2 to the left 2 units then shift downward by 2 units.

Explanation of Solution

Given information :

The function is g(x)=|x+2|2  .

Use the definition of vertical and horizontal shifts of graphs,

When graph of f(x)=|x| is given, then for function g(x)=|x+2|2 , shift the graph of f(x)=|x| to the left 2 units then shift downward by 2 units.

b.

To determine

To describe how the graph of the function can be obtained from the graph of y=|x| .

Expert Solution

Answer to Problem 17E

The graph of g(x)=|x2|+2 is obtained by shifting the graph of f(x)=x2 to the right 2 units then shift upward by 2 units.

Explanation of Solution

Given information :

The function is g(x)=|x2|+2 .

Use the definition of vertical and horizontal shifts of graphs,

When graph of f(x)=|x| is given, then for function g(x)=|x2|+2 , shift the graph of f(x)=|x| to the right 2 units then shift upward by 2 units.
