b) x=t22t, y=t
c) x=sin2t, y=sin(t+sin2t)
d) x=cos5t, y=sin2t
e) x=t+sin4t, y=t2+cos3t
f) x=sin2t4+t2, y=cos2t4+t2

Consider the parametric equation,
image
This equation's graph matches with that of (V).
As t goes to infinity, both x and y go to infinity. The graph must also contain the point (1,0) achieved at t=0
This function should not have any oscillatory behavior.
The parametric equations match graph (V).

x=t22t, y=t
image
The equation's graph matches with that of (I).
As f goes to infinity, both x and y go to infinity. The only graphs that have this behavior are (V), (I) and (IV). The graph must also contain the point (0, 0) achieved at t=0 Only graph (I) satisifies this requirement.

x=sin2t, y=sin(t+sin2t)
image
This equation's graph matches with that of (II).
The graph must contain the point (0, 1) achieved at t=π2. Graph (II) is the only graph that satisifies this.

xcos5t, y=sin2t
image
This equation's graph matches with that of (IV).
The graph must contain the point (1, 0) achieved at t=0. Graph (IV) is the only graph that satisifies this.

x=t+sin4t, y=t2+cos3t
image
This equation;s graph matches with that of (IV).
As t goes to infinity, both x and y go to infinity. The the onli graph that have this behavior are (V), (I), and (IV). However, graph (IV) is the only one that shows any oscillatory behavior.

x=sin2t4+t2, y=cos2t4+t2
image
This equation's graph matches with that of (III).
The only graphs that exhibit oscillatory behavior are graphs (III), (II), (IV), and (VI). The graph must also satisfy the fact that the point (0, 0) cannot be a point on the graph. Graph (III) and (IV) satisfy this requirement.
For graph (IV), as t goes to infinity, both x and y go to infinity . This is not the case for these equations.
