Absolute value functions A special type of piecewise function
The graph of has the following characteristics: • The graph has vertex (h, k) and is symmetric to the line x = h. • The graph is V-shaped. It opens up if a>0 and down if a<0. Graphing absolute value functions
The graph is wider than the graph of if • The graph is narrower than the graph of if Graphing absolute value functions (continued)
