Absolute Value Equations with Fewer than Two Solutions You have seen that absolute value equations have two solutions when the isolated absolute value expression is equal to a positive number. When the absolute value is equal to zero, there is a single solution because zero is its own opposite.

For absolute value equations multiplied by a constant ,if, then the graph is compressed, and if, it is stretched. Also, if a is negative, then the graph opens downward, instead of upwards as usual. More generally, the form of the equation for an absolute value function is. Also: The vertex of the graph is.
About absolute value equations. Solve an absolute value equation using the following steps: Get the absolve value expression by itself. Set up two equations and solve them separately.
A2.5.4 Solve equations and inequalities involving absolute values of linear expressions.
Purplemath. Taking the absolute value of a negative number makes it positive. For this reason, graphs of absolute value functions tend not to look quite like the graphs of linear functions that you've already studied. However, because of how absolute values behave, it is important to include negative inputs in your T-chart when graphing absolute-value functions.
Section 3.2 Absolute Value Graphs A2.5.5 Determine the equation of a function as a variation or transformation of the general form of the equation for the basic family of the function.
