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.

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'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 …

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.

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

I had some trouble with this when I started out, so to help others, here is the method I used for graphing quadratics. So, you want to first find the x-intercept and the axis of symmetry from …

We can think graphs of absolute value and quadratic functions as transformations of the parent functions |x| and x². Importantly, we can extend this idea to include transformations of any …

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 solve quadratic equations, and how to analyze and graph quadratic functions.
