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

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 about quadratic equations and functions with detailed explanations and practice problems on Khan Academy.

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

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

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.

Graph quadratic functions given in any form.

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 function …
