For the one about concavity, was it concave down??? And also for the one about the intervals when it was concave down and decreasing, i got -2<x<-1 and 1<x<3???
Thanks for the boast of confidence you guys I just hope I won’t be disappointed in July.
Multiple choice section was about the same for the most part. The non-calc was maybe a little harder than usual.
The big difference was the FRQs, I felt they were harder than previous years, especially slope field m and b values, and coordinate point tangent is vertical.
For the tangent vertical one I couldn’t get a number I just got an equation with a bunch of square roots.
Did anybody get m=1 and b=1 for the last FRQ?
@RHSclassof16 im 100% sure thats the right answer,
Yay.
Is ~80% MC and ~75% FRQs enough for a five?
@RHSclassof16 Yep
@Batmen Yeah that’s well above what you need for a 5. If you get 65% MC and 60% FRQ’s you have a shot at a 5.
Was this free response or mc that the 350 was on?
The 350 was for free response for the RRAM approximation question
Phew. I don’t really care about the score for myself, but my teacher has been saying that I’ll get a 5 since the beginning of the semester. I’d really hate to dissapoint him.
I think the RRAM open ended was 350, it was like an average value or something of a velocity function
@Kylemcgrogan the bike one?
@NIHHIHH Now that I think about that one I remember getting a really large number for that one because of the absolute value. I remember 350 as an answer for something though. Maybe I’m mixing another problem up with that one.
How did you do that m and b value question? I picked a slope from the slope field and used its y and x value to find y=mx+b. Not sure if that’s right.
i think so

a, now delete the question, illegal to post it, net change theorem
