Eliminate the parameter.
x = t + 4, y = t2 (5 points)
y = square root of x + x + 4
y = square root of quantity x minus four
y = x2 + 16
y = x2 - 8x + 16

Last option

Step-by-step explanation:

We have the following equations:

The parameter that we must eliminate is t.

To eliminate the parameter we must clear t from both equations:

if    and

So:

We square both sides of the inequality
