To plot the graph of a quadratic function you must first create a table of values. Then choose suitable axes that will allow all these values to be plotted. Plot the values, then draw a smooth curve through the points.

## Summary/Background

These curves are called

**quadratic curves**. When you plot them on a graph they are shaped like a hill or a valley. They always have a vertical line of symmetry going down through the middle.## Software/Applets used on this page
