b is wrong, you were fine up to and including cancelling the (x+2) terms, at that point you should just substitute x=-2 and evaluate the expression, I'm not sure what you actually did after this...

c is really easy, just plug in pi and evaluate it

same with d

e you made a mistake in the last step (when rationalizing your denominator)

on 7 you wrote down the correct formula, but then didn't actually use it.... Follow the formula...

6, well they are both pieces of the piecewise function are continuous, so the only possible problem would be where they are joined together, so establish they meet at this location and you are in business

4 / sqrt(2) = [sqrt(2) * 4] / [sqrt(2) * sqrt(2)] = 2 * sqrt(2)
