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
