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

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 vertex form. Here, Sal graphs y=-2 (x-2)²+5. Created by Sal Khan.

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

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 …

Graph quadratic functions given in any form.

This topic covers: - Solving quadratic equations - Graphing quadratic functions - Features of quadratic functions - Quadratic equations/functions word problems - Systems of quadratic …

An example for a quadratic function in factored form is y=½ (x-6) (x+2). We can analyze this form to find the x-intercepts of the graph, as well as find the vertex.

The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math. We’re not big fans of you memorizing formulas, but this one is useful (and …

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