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.

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 …

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

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.

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

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 …
