Don't overthink it; the problem itself says that it's pre-college-level stuff.

>D contains all points P that lie on the curve y(x)
Set t to different values, and see what you get. D is just the graph defined by the function y(x) for different values of t.

No matter what t is, some things will always be true about that function. State what those things are.
