POSSIBLE SOLUTIONS

(a) Analysis for f(x) = 9 + 8x - x^2. (Using actual distance function.)

(b) Analysis for f(x) = - x^4/20 + 11/15 x^3 - 17/5 x^2 + 24/5 x + 6.

We use a sum squared function (which we explain below) to minimize for solving two distance equations will not work in this case.

(c) Analysis for f(x) = 8 + 6.2 x - 1.7 x^2 + .1 x^3.

Using actual distance function.
