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.

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.

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