Limits

For (a) is it 2 or undefined?
Is my answer for (b) and (d) correct??

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).

I changed (b) to undefined since the the limit from both sides don't equal to each other
I changed (d) into -1

The new answers are correct.
