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 given in the standard form ax²+bx+c. For example, graph 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 …

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 …

Once you've graphed the vertex, move 1 unit to the left and right of the vertex to get two new "x" values to find more points to complete your graph. For each new value of "x", you use it in the …

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.

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.

Graph quadratic functions that are given in factored form. For example, graph y= (x-4) (x+2).
