Unlike the graphs of linear functions, the graphs of quadratic functions are nonlinear: they don't look like straight lines. Specifically, the graphs of quadratic functions are called parabolas.

Learn how to graph any quadratic function that is given in vertex form. Here, Sal graphs y=-2 (x-2)²+5. Created by Sal Khan.

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

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.

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

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

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 …

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.

To graph quadratic vertex-form equations, we identify the vertex point, plot random (x, y) points nearby, then connect them to make a parabolic shape. We can do something similar for …
