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.

Step 2 – Create a table for the x and y values that you will calculate to plot the graph. Step 3 – Find the values for y. Start with x = -2. When x = -2, y = 0. Write this in the table.

You can make a bar graph in Excel by first selecting the range you want to depict, and then using the dropdown menu to select the desired chart.
