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?

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
