Solutions

Chapter 2.5, Problem 12E

a.

To determine

To describe how the graph of the function can be obtained from the graph of f .

Expert Solution

Answer to Problem 12E

The graph of y=32f(x) is obtained by shrinking the graph of f the shift 2 left and 2 down the graph will be twice smaller

Explanation of Solution

Given information:

The function is y=32f(x)

Use definition of vertical shifting and horizontal shrinking of the graph,

When graph of f is given, then for function y=32f(x) , is obtained by shrinking the graph of f the shift 2 left and 2 down the graph will be twice smaller

b.

To determine

To describe how the graph of the function can be obtained from the graph of f .

Expert Solution

Answer to Problem 12E

The graph of y=2f(x) is obtained by stretching the graph of y=2 then shift 2 right and 2 upward and the graph will be twice smaller

Explanation of Solution

Given information:

The function is y=2f(x)

Use definition of vertical and horizontal stretching of the graph,

When graph of f is given, then for function y=2f(x) , is obtained by stretching the graph of y=2 then shift 2 right and 2 upward and the graph will be twice smaller
