**MathMate**, Wednesday, December 21, 2011 at 9:30amWe do not see the graph, so we're unable to find f(-4), etc.

On the other hand, with the graph in hand, you could look up -4 in the x-axis, go vertically until you hit the curve then go horizontally to find the corresponding value for y, which equals f(-4) in this case.
