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

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

Webnext, we take care of what's happening 'outside of' the absolute value.

The output values of the absolute value are equal.

Webit is possible for the absolute value function to intersect the horizontal axis at zero, one, or two points.

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.

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