Answer:

The correct choice is C

Step-by-step explanation:

The given curve is described by the parametric equations:

x=4-t

y=t^2-2

Let us eliminate the parameter by making t the subject in the first equation and substitute into the second equation;

t=4-x

We substitute this into the second equation to get:

y=(4-x)^2-2

This is the equation of a parabola whose vertex is at (4,-2)

The correct choice is C
