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 graphical representation of quadratic equations are based on the graph of a parabola. A parabola is an equation of the form y = a x 2 + bx + c. The most general parabola, shown at the right, has the equation y = x 2. The coefficent, a, before the x 2. The vertex 2, the vertex is (0,0).
