To determine

## To sketch the graph of f(x)=[|2x|] by using the function graph f(x)=[|x|] .

Expert Solution

### Explanation of Solution

Given information:

The function is f(x)=[|x|]

Graph :

the graph of function f(x)=[|2x|] obtained as:

Interpretation: from the above graph it is observed that when f(x)=[|x|] is given, the graph of the function f(x)=[|2x|] is obtained by horizontal stretching the graph of f(x)=[|x|] by the factor of 12 .
