How to Create a Graph Traced by Parametrics

Question

The question is as follows:

What graph is traced by the parametric equation $(x,y) = (t, 4-t^2)$?

I am unsure as how I can create a graph given that parametric equation. Any help will be greatly appreciated.

Answer 1

Hint: Eliminate $t$ from the following equations to get an equation $y(x)$.

$$x(t) = t$$ $$y(t) = 4-t^2$$
