A polynomial graph passes through the points (-3, 0), (0, 48), and (4, 0). From left to right, the graph increases through (-3, 0), decreases to (4, 0), and increases after (4, 0). Which of the following could be the equation of the graph above?

Question 2 (essay worth 10 points) (03.02 mc) in δabc shown below, point a is at (0, 0), point b is at (x2, 0), point c is at (x1, y1), point d is at x sub 1 over 2, y sub 1 over 2, and point e is at the quantity of x sub 1 plus x sub 2 over 2, y sub 1 over 2: triangle abc is shown. point d lies on segment ac and point e lies on segment bc. a segment is drawn between points d and e. point a is at the origin. prove that segment de is parallel to segment ab.
