Question

In exercises 10-12, sketch the curve represented by the parametric equations. Then eliminate and write the corresponding rectangular equation whose graph represents the curve.
10. x=t2-6
y=1/2t-1

answer: t=2y-6= (2y+2)2-6
=4y2+8y-2

Answer 1

as you can see in the other answers, yes 4y^2+8y-2
