Differentiation questions.

Hi guys I have a few questions regarding my study guide. You can view my practice test under the following link.

http://www.math.utep.edu/Faculty/cmmundy/Math%201411/Exams/Module%203/Practice%20Exam%20mod%203.pdf

On question four part b how can you determine whether f(x) is differentiable at x=-2?

How would I solve # 5 part c and e and #11 part e?

Finally how would I solve # 12?

Thank you so much guys. My final is tomorrow and I’m just trying to cram everything in. I appreciate your help!
