The graph of the quadratic function y = a x 2 + b x + c has a minimum turning point when a> 0 and a maximum turning point when a a <0. The turning point lies on the line of symmetry.

We consider positive powers of a rational generating function F (x, z) of the variable z whose numerator has degree at most 1, denominator has degree 2, and where coefficients are functions of x. Many ...

The graph of the quadratic function y = a x 2 + b x + c is a smooth curve with one turning point. The turning point lies on the line of symmetry. Graph of y = ax2 + bx + c ...
