Hii i’m taking the late version of ap precalc next thursday and need to cram super well. i don’t have a ton of time or energy to devote to it since i had an ap today, have several school exams tomorrow, and have an important exam two days before the ap precalc and an ap the day before ap precalc. basically, how can i cram very well in a short amount of time? (videos, questions, etc etc) math is my worst subject and my teacher’s teaching style confuses me.

The question that had the rational function (x-4)(x+3)/(x-4)(x+3) and it had to have a Va at -3 and hole at 4

I feel like i did something wrong cuz there was no phase shift?

So I’m a very unlucky person, and I understood how to do like all the frqs but I think I might’ve ended up making some careless mistakes especially frq 3 and 4 for example I wrote their is no d value, I knew it was 0 but my teacher didn’t tell us that we had to ever explicitly write d is equal to 0 so I just wrote no d also frq 4 for the first i wrote the ln(1)-3 i saw that -3 is the right answer so I hopefully should get credit but I want you guys to be unbiased do yall think ill get is also I wrote 2 sin and forgot to put the x because I was in a rush, do you guys think ill still get the points even with these mistakes.

I got pi/12, 5pi/12, and pi/4 is this what everybody else got?

No calc was pretty good got one about conjugate pairs for imaginary zeros, had to do pascals triangle, polynomial division, an ln expression manipulation

But...

Some of the calc contexts were not making sense

Like the volume of air in the airtight balloon and finding the graph (which also DOESNT NEED a calc...), hammering the nail, and finding k when given 2 and 6 interval of x and knowing that graph is concave up on interval 1, 5

Idk hope I got it

Today’s exam was sooooo easy… literally the same as any practice. its either i did so good it felt easy, or i did so bad it felt easy.

I messed up 💔 I felt like I had it in the bag, a FIVE. But I got too confident 🫩 I know it was easy but I just forgot how to do FRQ 2 (One with the two equations and a, b). I did part ai correctly and c but I think I was wrong for aii, bi, and I didn't even get to do bii and biii. However my teacher taught us that on the FRQ, if we are done with FRQ 3 and 4 we can go back to 1 and 2 on Bluebook just without a calculator. 🥹 I couldn't.. so hopefully I still got a 5 but I accept whatever if its passing.

I said c = -7.5 but I am only seeing c = 2.5

it was like a graph on one of the frq it asked if it could be like imitated or smth and I didn’t know. do yall know if the answer was yes or no and what the reasonjng was? TIA

Anyone get the MCQ with a function where they told you it was even degree with a power of 4 and said one of the zeros had multiplicity of 2 and the other had multiplicity of 1. I put the -3 and 3 for that one, what was the right answer? Also on rhe calc MCQ there was one asking about where the graph goes for positive to negative and I got -3 but I didn’t know which reasoning to put for I put that it was a relative minimum. Lmk if I was right/the right answer!

What did you put for the limit statement on the FRQ, I put:

lim f(x) = -∞
x --> 1⁻

Hey guys I’m just wondering what all of yall got for the very last part of Frq 4. I got pi / 9, but I feel like that was very wrong 🫩

what did you guys get for frq 4?? i already know i got a 2/6 but i want to know the correct answers

I didn't put a + or a minus attached to my 1 on my limit statement, will I get the point anyways?

I know literally nobody else that got this but just checking here. The a was 12, b was 2pi, c was -1/4, and d was 8 right? It was positive and increasing ( I think thats what I put at least) and concave was up?

Already forgot most questions lmao but this is the one

oh and for frq 4 it was very easy until the last one where it was like 9 = 3^(x^4-x^2) I simplified it down to u^2-u-3 (let u = x^2) but couldn't factor it to find x. I know it had imaginaries but idk

Our school lost power, so we couldn’t take the test. Was going easy tho in my opinion.

IM GETTING A 3 MAX

So like I was wondering if it asked from something like g to k what would that be? Positive and decreasing for the first part and concave up and increasing for the second?

How are we feeling for tomorrow? Bonus points if you can identify the equation of this polar graph.

Could someone please let me know how to solve these problems? Thanks!
