10-101.

Give an example of:

Any set of equations where $x = x\left(t\right)$ and $y = y\left(t\right)$.

1. A graph that can be represented by parametric equations, but is not of the form $y = f\left(x\right)$.

2. A graph that can be represented in the form $y = f\left(x\right)$, but not by parametric equations.

This is not possible. Why?
