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

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

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.

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

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