Hey asilvester635.

Hint: For (a) consider that a limit has to be the same from both the left and right directions. (Your answers are not correct). - Feb 15th 2013, 07:37 AMasilvester635Re: Limits
I changed (b) to undefined since the the limit from both sides don't equal to each other

I changed (d) into -1 - Feb 15th 2013, 02:57 PMchiroRe: Limits
The new answers are correct.
