A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in this Bitesize KS3 maths video.

An inverse function graphing calculator will allow you to graph functions quickly and precisely, which will help you visualize how these graphs behave.

The graph of y = f (x) where f (x) = x 2 is the same as the graph of y = x 2. Writing equations as functions in the form f (x) is useful when applying translations and reflections to graphs.

Windows 10 Build 19546 includes a special Graphing Mode for Windows Calculator that looks surprisingly nice.
