2. Evaluate the following integrals:
(a) (3 points) h(? )?(t ? ? )d?
(b) (3 points) ?(? ? 1)?(t + 1 ? ? )d?
(c) (3 points) e ^(??) ?(? ? 1)d?
Please explain your work, and bounds for a and b are ?? to ?, I have answers but I am not sure I am right and would like to see how someone with more experience does these problems. Thank you!
