A rectangle is inscribed between the x-axis and the parabola y=9-x^2 with one side along the x-axis. One side in touchin the x- axis and the opposite two vertices touch the parabola.
A) Suppose the point (2,5) is the vertex of the rectangle on the original parabola. Use this point to verify your equations from parts a) and b).
I don't really get how I can do that.

Part a) asked for the equation for the area of rectangle- i got -2x^3+18x. Part b) asked for the equation after a horizontal stretch by a factor of 4- I got the y=2x*(-(1/4x)^2+9).
