Answer: Upper left corner
==============================================================
Further Explanation:
The piecewise function is broken down into three parts which I'll refer to as A, B and C (moving down the rows).
Part A is y = -4 but only if x is -3 or smaller. Points on this line include (-3,-4), (-4,-4), (-5,-4), etc. Basically any point where the y value is -4, and the x value is -3 or smaller.
Part B of this piecewise funciton is exactly one point which is (2,0). We plot y = 0 but only when x = 2.
Finally, part C is the horizontal line through y = 3 but we only graph this line if x is larger than 2. Two points on this line are (2,3) and (3,3). The point (2,3) is an open circle because of the fact that x > 2. So x = 2 is not allowed for this piece.
Put this all together, and you get the graph shown in the upper left corner as the final answer.
Note: the bottom left corner is very close to the proper answer, but the presence of an open hole at (-3,-4) is why this is not the actual answer. We are including this point as part of the first piece. This point is included because of the "or equal to" as part of the inequality.
