Hello,

I need help using my TI 84 to figure out this 4 part question. My professor went over it way to quickly in class, when showing us how to do it on the TI 84, I believe its only a few quick steps for each part though.

EDIT: I have figured out part d, but am still struggling with parts a, b, and c.
