Write a set of equations for the piecewise-defined function shown on the graph at right. Be sure to include the domain for each part of the function. 9-119 HW eTool (Desmos). 

Look at the two pieces of the function. Notice the open and closed circles, and the values at .

Piecewise function, with 2 unconnected sections: Left: ray, starts with open point (2, comma 1), passing through the point (0, comma negative 3). Right: ray, starts at open point (2, comma 3), passing through the point (7, comma 8).
