Question

A curve is described by the following parametric equations: x = 4-t y = t^2 -2

Answer 1

Answer:

Step-by-step explanation:

Given

$x=4-t$

and $y=t^2-2\quad \ldots(i)$

So, $t=4-x$

Substitute the value of $t$ in $(i)$

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

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

So it represent a parabola shown in the figure
