Absolute Value Function Graphs Math
Because of this absolute value functions have graphs which make sharp turns where the graph would otherwise have crossed the x axis.
Absolute value function graphs math. F x a x h k. In this worked example we find the equation of an absolute value function from its graph. Because absolute value doesn t care about the sign you can effectively just remove the negative on the 1 2. Absolute values are never negative.
Purplemath explains how these graphs work and how to get full credit when doing this sort of graphing. Now that the equation has been simplified to y 1 2 x 6 10 you can get to graphing. When a is negative the v shape graph opens downward and the vertex is the maximum. It is linear if the variable x has a power of 1.
Y 1 2 x 6 10. If k 0 it s also reflected or flipped across the x axis. The graph of absolute value function has a shape of v or inverted v. This lesson is about graphing an absolute value function when the expression inside the absolute value symbol is linear.
How to graph absolute value functions. The general form of the absolute value function is.
