Thank you for the first two questions, but Sir I unfortunately don't see q3 and 4 and my lab starts in an hour :(

I was planning on doing it this afternoon, I'm sorry in class at the moment. Do you still want it later?

Totally understandable, sir! thanks for the response. if you do get a chance i'd appreciate it thanks

any other colleagues that could possibly submit the sols?

s.h_math (https://biology-forums.com/index.php?action=profile;u=1067569) I only consult my colleagues when I don't know how to answer a question, these are in fact easy :P

Here's what I was working on last night before I stopped. Technically, it is the answer to Q3.

Furthermore, you should time ask days ahead of time

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.
