If the constant is between 0 and 1, we get a vertical compression.

Graph to find the points satisfying an absolute value inequality.

Webkey concept • vertical dilations of absolute value functions if | a| > 1, the graph of f(x) = | x| is compressed horizontally.

Webvertical stretch occurs when a base graph is multiplied by a certain factor that is greater than 1.

The stretching or compressing of the absolute value function y = | x | is defined by the function y = a | x | where a is a constant.

Webnote that these equations are algebraically equivalent—the stretch for an absolute value function can be written interchangeably as a vertical or horizontal stretch or.

The graph below shows a function multiplied by.

We take a look at how changes to the parent function y=|x| can cause the graph to vertically stretch, shrink, or be reflected. more.

The most significant feature of the absolute value graph is the corner point at which the graph changes direction.

Webnote that these equations are algebraically equivalent—the stretch for an absolute value function can be written interchangeably as a vertical or horizontal stretch or.

Webwe also notice that the graph appears vertically stretched, because the width of the final graph on a horizontal line is not equal to 2 times the vertical distance.

The graph opens up if a >.

When a function is vertically stretched, we expect its graph’s y values to be farther from.

The output values of the absolute value are equal.

Webif the constant is greater than 1, we get a vertical stretch;

This results in the graph being pulled outward but retaining the input values (or x).
