Thread: In the expression, 1/(y+6), why can't y equal 0,3,-6, or -3?

I understand that y can't equal -6 because it will make the denominator 0, but why the other numbers?

y could equal any of the other numbers...who told you otherwise?

You need to post the entire question. The part you quoted makes little sense as is.
