How do you solve a piecewise function? Easy Points?

You know how to draw the graphs for y = -2 and y = 3, right? They're just horizontal lines ping through -2 and 3 respectively on the y-axis. The way you draw f(x) is you draw y = -2 on the left side of the y-axis (i.e. where x < 0), and you draw y = 3 on the right side of the y-axis (where x > 0). Now, on the y-axis, to show that the function takes -2 when x = 0, you put a dot on -2, and a small hollow dot on 3, to show that the function doesn't take the value 3 on the y-axis, but that every point beyond the y-axis will take the value 3.
