In Chapters 2 and 6 you saw some examples of piecewise graphs. At right is an equation for a piecewise graph.
This equation states that for non-negative input values the top rule is used and for negative input values, the bottom rule is used.
For example, for an input of x = 3, the output is 3 + 2 = 5 and therefore the point (3, 5) is on the graph. However, for an input of x = –2, the output is (–2)2 = 4 and therefore the point (–2, 4) is on the graph. Use various other input values and sketch a graph of this piecewise function. 10-87 HW eTool (Desmos). Homework Help ✎
