### 3.5Absolute Value Functions

Absolute Value Function
• Has the form
• An absolute value functions has graph that forms a V
To graph absolute value functions
• Find the vertex.
• (Set the value inside the abs signs equal to zero)
• Make a table of values (an x/y chart).
• Choose enough x-values to create both legs of the V.
• Plot the points and connect them.

Characteristics of Absolute Value Functions
• If the function is ______________, the V opens upward. If the function is ___________, the V opens downward.
• If there is a number added or subtracted inside the absolute value bars, the V is shifted ________________.
• If there is a number added or subtracted outside the absolute value bars, the V is shifted ________________.
• If the function is multiplied by a coefficient, the V gets narrower or wider.
