Absolute Value Functions

2
Absolute Value Function Has the form An absolute value functions has graph that forms a V

3
To graph absolute value functions 1.Find the vertex. 1.(Set the value inside the abs signs equal to zero) 2.Make a table of values (an x/y chart). 3.Choose enough x-values to create both legs of the V. 4.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.
