# The most famous parabola

The most famous parabola is:

`y=x^2`

To remember this think

There are 2 parabolas in `x^2`

And it's very easy to work out what `y=x^2` is if you plot figures of `x` against `y`.

`x=2`

Therefore

`y=2^2=4`

`x=1`

Therefore

`y=1^2=1`

`x=0`

Therefore

`y=0^2=0`

`x=-1`

Therefore

`y=-1^2=1`

`x=-2`

Therefore

`y=-2^2=4`

Which can be plotted as
