Document Summary

A quadratic function of x is a function that can be represented by a form f (x) = ax ^ 2 + bx +c. A, b, c are real numbers and is not equal to 0. Equation: z = x ^ 2 - y ^ 2. Z is the quadratic function of x and y. The graph of z = x ^ 2 - y ^ 2 can be viewed as the saddle of the graph shown in the textbook. The graph of f (x) = ax ^ 2 + bx +c, a is not equal to 0 is a parabola. A parabola is a type of curved line on a graph which is shaped as an open plane curve. The vertex of a parabola can be two things: A vertex usually refers to a point where two or more line segments meet but refers to slightly different when it comes to parabolas.
