The most famous parabola

The most famous parabola is:

`y=x^2`

 

To remember this think

There are 2 parabolas present in x squared

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

Parabolas can be plotted on a graph
