You just need to take look at the graph. If you know what f'(x) (i.e. f prime of x ) it should make sense.Where of the graph though?
We can see clearly at [4, 6], f'(x) = -3.

Yeah, I too have to admit that the TEX code on this forum is awkward for those who aren't that familiar with it. I just use the TEX/Equation feature in Microsoft Word half of the time, looks the same to the average user.I was rushing for time to not get beaten by @CM_Tutor lol. Embarassing to say it took me a few minutes to type it out in TEX, and it would've been awkward to get ninja'd by CM.
Your contributions are definitely appreciated and valuable. I definitely don't see it as a competition, just making humour of the situation lol.@B1andB2 and @username_2, would you please explain what is humorous about my posts here?

I'm quite serious that I don't want to be a cause of participants feeling discouraged from contributing here. My intention is to be helpful, but if contributing as I do is not having that effect then I need to reflect / re-evaluate.
ye didn't mean to annoy you. Just found it funny that you're s0 good at helping that you have had to think about "maybe im doing too much". That I found funny but I respect too. You certainly aren't stopping people as well so yeah. (although i didnt expect to be called out like this lol)@B1andB2 and @username_2, would you please explain what is humorous about my posts here?

I can restore it for you if you likeDunno, it seemed like a minor thing... but now it has caused a mess for some reason
Would you like me to post it again?
Drdrawn’s solution after I liked it

I think it's more harmful than good if someone was to post an incorrect solution with flaws, imagine if that person felt confident with an incorrect solution and if they replicated it in an exam or somewhere else, they would be in a bad position so having some individual in the community who is mostly, if not, always correct post solutions gives that extra reassurance. It also helps for people posting solutions to get confirmation whether their method is valid/not and seeing someone else's way of doing it helps broaden their thinking.I certainly don't want to be a discouragement to anyone to contribute.
It is DrDawn not Drdraw, hence your difficulty in tagging...What I want to know is why @Drdrawn deleted his post. I can’t seem to tag him either
Don't feel bad, DrDawn, and it hasn't caused conflict. I just saw some irony in @A1La5 commenting on being ninja'd by @yanujw when it was actually @DrDawn who answered first, but that original answer had been removed.I deleted my post after you had liked it so I thought you acknowledged/understood the solution, and thus it had served its purpose... except now it seems to have caused some conflict...
