You can also plot things parametrically. For example, here you will find an example of a sideways parabola.

It was not plotted as two sqrt functions, but rather as a shifted polar form converted to Cartesian. You can adopt this to plot any x(t),y(t). For circles, this would be much simpler than parabolas.
