Graphing Quadratic Functions (Jump to: Lecture | Video )

Quadratic Function
A Quadratic Function is a type of nonlinear function.

Figure 1.

Above are two examples of graphs of quadratic functions. These are called Parabolas.

Figure 2.

On the left, we have a quadratic equation. We can graph it by plugging in a series of "x" values to determine the resulting "y" values. The table on the right shows how we calculated our ordered pairs for graphing.
