Note: You can't go through algebra without seeing quadratic functions. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown. In this tutorial, get introduced to quadratic functions, look at their graphs, and see some examples of quadratic functions!ou can't go through algebra without seeing quadratic functions.

Non-linear graphs are everything else. The straight lines are in the form of y=mx+b. The first non-linear graph we have is a parabola which is the shape of the graph when either x or y is squared. A parabola looks like a U, but the ends are not parallel.If you graph y=x^2 (the most basic one), you'll see a parabola. The next non-linear graph is where either x or y is cubed.he straight lines are in the form of y=mx+b.
