***AP Calculus AB 2015-2016 Thread***

@appgodxoxo You mean 8(x-1)^2

@YoohooAddict
Yeah, true. Ok, you’re right.

So I, II, and III were all right.

Hello. I recently took this exam (this morning in fact) and I particularly found it to be easy. Although I am only in the seventh grade, the fifth free response question was challenging. I feel as if I received a 5. That funnel was sketchy though.

What was option II. I remember trying an example on it and it didn’t work. @appgodxoxo @Aleksandr7

Wouldn’t the inverse function one be 1/5?

Wow, congrats @catsdogscats2016 and hope you did well. It’s impressive for a seventh grader to know calculus imo!

Hey everyone, I was wondering if anyone remembered the choices/answer for the question that asked about extreme value theorem because we werent even taught that lol

@Chrysanthemum14 that’s right for the e^10 one.

inverse i think was 1/2

And @catsdogscats2016 great! What a great start to your ap career! Hope you get a 5! You obviously must know your stuff for a 7th grader. What’s your plan next year?

i put that min and max have to occur the answer choice because it had closed interval. i am not sure if i am right tho am i?

@desiboy1998 by the EVT i think thats right

@BioNick I’m pretty sure I got that one wrong. The answer I believe was something about there being a relative extrema in the domain [a,b]. I thought it was another word for mvt tho so I chose another one which was technically true.

@appgodxoxo Its probably 1/5 but I cant remember if I put 1/5 or 1/2 because the formula is 1/ (f’(g(x))

@silverhawk5 Yes, that is the formula. When x was 5 (where they wanted the derivative), g(x) was 2. What was f’ at 2? 5. 1/5. Answer is 1/5.

Just remember this basic property: if g(x) is the inverse of f(x), then f(g(x)) = x. Differentiate both sides to derive the formula for inverse derivatives.

man was the multiple choice calculator section that easy? cause i finished so early.

There was a mcq question. I don’t know what it asked but at the end I got e^(ln2 + 1) and factored it to e^ln2 (e^1) then simplified it to 2e.

got that too @YoohooAddict

Yeah @YoohooAddict me too. 5 club here we come!

For the inverse one I did Inversef’(b) = 1/f’(a) and plugged in the points to get my answer.
