The graph of a quadratic function is a parabola, which is a "u"-shaped curve. In this article, we review how to graph quadratic functions.

Learn how to graph any quadratic function that is given in standard form. Here, Sal graphs y=5x²-20x+15.

Graph quadratic functions that are given in the vertex form a (x+b)²+c. For example, graph y=-2 (x-2)²+5.

One of the common forms for quadratic functions is called vertex form, because it highlights the coordinates of the vertex of the function's graph.

Part of the beauty of linear equations is that we can write them in different (but equivalent!) ways to highlight different features. Whether we want a particular point, an intercept, or the slope of …
