**Sally**, Tuesday, June 16, 2009 at 6:10pmif x=-3, then y=-3, not zero:

y=-3^2-6-3

y=6-6-3

y=-3

Does this make sense?

if x=1, then y=0, you are correct:

y=1^2+2-3

y=1+2-3

y=3-3

y=0

Does this make sense?

Hope this helps!! :-)

**PsyDAG**, Wednesday, June 17, 2009 at 11:38amSally has made a mistake. (-3)^2 = 9 not 6.

y=-3^2-6-3 = 9 - 6 - 3 = 0

The second value solution is correct.

I hope this helps a little more. Thanks for asking.
