John I. Moore Figure 1. Tracking weight for the year In this article I’ll use my open source library, GraphLib, to demonstrate the basics of graphing mathematical functions in Android.

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph - points are plotted as coordinates and joined by either a ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function y = a x 2 + b x + c is a smooth curve with one turning point.
