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

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.

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 problems.

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.

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

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.

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

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 the equation.
