Now we are dealing with cubic equations instead of quadratics. From Part I we know that to find minimums and maximums, we determine where the equation's derivative equals zero. The equation's derivative is 6X 2-14X -5. and when this derivative equals zero 6X 2-14X -5 = 0. the roots of the derivative are 2.648 and -.3147

In order to completely define a cubic function, you need four distinct points. So it is not very surprising to me that you are getting these conflicting results, since two points leaves a great deal of ambiguity. That said, if you know in advance your equation looks like y = a x 3 + b, then two points is enough to specify it.

The point x=a determines an absolute maximum for function f if it corresponds to the largest y-value in the range of f. 6. The point x = a determines a relative minimum for function f if f is continuous at x = a , and the first derivative f ' is negative (-) for x < a and positive (+) for x > a .

Uniform cubic B-spline curves are based on the assumption that a nice curve corresponds to using cubic functions for each segment and constraining the points that joint the segments to meet three continuity requirements: 1. Positional Continuity (0 order): i.e. the end point of segment i is the same as the starting point of segment i + 1. 2. The graphs of these functions are interesting and useful as models, because we can use them to find maximum and minimum values. Cubic and Quartic Functions A cubic function is a function whose highest power of the variable is 3; a quartic function is a function whose highest power of the variable is 4. Given a function f(x) and a point P1(x1, y1), how do we calculate the tangent? Finding the tangent means finding the equation of the line which is tangent to the function f(x) in the point P1(x1, y1).
