Plot a Graph
(Purdue University)

Graph the function given by .

The graph consists of two separate branches. The left branch is a ray with slope 1 containing the point (x, y) = (-1, 2) (which is the endpoint of the ray). The right branch is a parabola (opening up) with vertex at (x, y) = (0, 0). Notice that the right branch starts at, but does not contain, the point (x, y) = (-1, 1); there is a jump in the graph at this point.
