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.

The Simplest Quadratic. The simplest Quadratic Equation is: f(x) = x 2. And its graph is simple too: This is the curve f(x) = x2. It is a parabola. Now let us see what happens when we introduce the a value: f(x) = ax2. 1  Larger values of a squash the curve inwards.2  Smaller values of a expand it outwards. 3  And negative values of a flip it upside down.he simplest Quadratic Equation is: f(x) = x 2.
