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. Created by Sal Khan.

We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world …

Learn how to graph any quadratic function that is given in vertex form. Here, Sal graphs 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.

We can interpret what the features of a graph of a quadratic model mean in terms of a given context. Created by Sal Khan.

Graph quadratic functions given in the standard form ax²+bx+c. For example, graph y=5x²-20x+15.

A system of equations that contains one linear equation and one quadratic equations can be solved both graphically and algebraically. Each method has its pros and cons. See an …
