Some errors/notes during my attempt: Q7) Didn't read the question and found range of f(g(x)) instead of its derivative. Q12) Solved at the end of the video Q19) Answer is D, solved the inequality in the wrong direction and even got the annotation wrong in the edit too XD If you spot any other errors, comment here and I'll append to this post.
Hi, thanks for sharing this! I have a question regarding Section 2 Question 2 and the last question, which is find all possible values of n, but when you write your solution as n=5(6k+1), why is k an integer not all real numbers? Could you please explain this? Thank you!
