Parametric equations have the form x=f(t)x=f(t)x=f(t) and y=g(t)y=g(t)y=g(t), where ttt is the [ ].
A
From left to right.
B
Parametric equations have the form x=f(t)x=f(t)x=f(t) and y=g(t)y=g(t)y=g(t), where ttt is the parameter.
C
At (3+5, 5+25)(3+\sqrt5,\,5+2\sqrt5)(3+5,5+25).
D
As ttt increases, the generated points give the curve a direction.
