Windows Calculator has a Graphing feature. We show all its features in Windows 11/10 that you can use to make mathematics more insightful.

The plot function creates a 2D plot with the slope-intercept form of the equation, and the (x,-10,10) part specifies the range of the graph, between the x values of -10 and 10.

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

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.
