  1. In Chapters 2 and 8 you saw some examples of piecewise graphs. At right is an equation for a piecewise graph: 10-84 HW eTool (Desmos). Homework Help ✎

  2. This equation states that for non-negative input values the top equation is used and for negative input values, the bottom equation is used.

  3. 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 = 16 and therefore the point (–2, 16) is on the graph. Use various other input values and sketch a graph of this piecewise function.

Complete the table in the eTool below to create a graph of the piecewise function.
