Rotating simple parabolas

Rotating $y=x^2$ by 90° clockwise or anticlockwise you have to remember.

Rotate $y=x^2$ clockwise $y=sqrtx$
Rotate $y=x^2$ anticlockwise $y =sqrt(-x)$

So first plot $y=x^2$

Try different values of $x$

And we plot this as

Draw out the famous parabola to start to rotate it

Now plot $y=sqrtx$

try different values of $x$

Now rotate the parabola clockwise remembering y=?x as we go

Now plot $y=sqrt-x$

try different values of $x$

Now plot this against the original graph.

Now rotate the parabola anticlockwise remembering y=?-x as we go
