# Drawing Quadratic and Cubic Graphs Math Review

math tutorials > drawing quadratic and cubic graphs

The plotting of quadratic and cubic graphs is a vast topic and can be done in various ways. The aim of this tutorial is to introduce you to the 2 types of graphs and the tabular method of drawing them (as we did for straight line graphs).

## Quadratic Graphs

The equation for a quadratic graph can be written as

*a, b,* and *c* are constants.

*y* has the power of 1.

*x* has a maximum power of 2.

The graphs of quadratic equations are called **parabolas**.

### Examples

These are all parabolas:

## Cubic Graphs.

Cubic graphs are in the form

*a, b, c* and *d* are constants.

*y* has a power of 1.

*x* has a maximum power of 3.

### Note:

You can calculate the intercepts of parabolas and cubics in the same
way as for straight lines.

For the x-intercept, put y = 0. (A parabola may have 2 x-intercepts,
a cubic 3).

For the y-intercept, put x = 0.
