Math Problem Statement
The graph of a piecewise-defined function is given. Write a definition for the function that best describes this graph.
-7 7 -7 7 x y
left parenthesis 2 comma 1 right parenthesis (2,1)
left parenthesis 0 comma 0 right parenthesis (0,0) left parenthesis negative 2 comma 2 right parenthesis (−2,2)
A coordinate system has a horizontal x-axis labeled from negative 7 to 7 in increments of 1 and a vertical y-axis labeled from negative 7 to 7 in increments of 1. The graph contains two branches. The first branch is a ray that starts at a labeled solid circle at (0, 0), rises from right to left, and passes through the plotted and labeled point (negative 2, 2). The second branch is a line segment that falls from left to right and extends from an open circle at (0, 3), through the plotted and labeled point (2, 2), to a solid circle at (3, 0).
