For the last one, I'm not entirely sure but first you find the point of intersection, then use the x-value as your "a".

THANK YOU for providing that, and I know I must submit my questions ahead of time. I've gotten the flu, so I am backtracked quite a bit. Apologies for bothering you during your class time.
