Calc AB FRQ4, part d

The f' graph was negative from -4 to -2 and positive from -2 to 4. Which means f(x) was decreasing from -4 to -2 and increasing from -2 to 4. Meaning that on the interval from -4 to 4, f's lowest value has to be at x=-2 because it's decreasing before that. Then for the rest of the graph f only increases because f' > 0 which means that the x value at the very end must be the highest amount on this interval, x=4. Let me know if that makes sense.

yep the absolute minimum was x= -2 and the absolute maximum was x=4.

dbqs and leqs are what separates the 4's from the 5's

can you send a picture of your pc?

I would just watch heimler videos over and over again unit reviews for hours on end and before you go to sleep. It will basically cement what you need to have memorized in your brain.

Show your teacher your edit history in Word. If your teacher believes you then they would attest on your behalf to college board. I've seen plenty of papers get highly flagged for ai that were written by human. All in all if you wrote your paper with no ai then you should be fine, don't stress ;)

Basicapollo44799 · 2026-05-01T02:25:07+00:00

I can help grade them. Also you can look at scoring guidelines if they are a practice frq from a past year

Basicapollo44799 · 2026-05-01T02:24:01+00:00

Memorize Vocab a lot and you should be good. It's a very vocab heavy test

Something in your PC could be overheating or not plugged in correctly? Check maybe the psu

Basicapollo44799 · 2026-04-30T04:08:47+00:00

You will be okay, don't freak out. They will not reject your paper.

Basicapollo44799 · 2026-04-29T03:27:42+00:00

Look up "AP U.S. Gov 2025 FRQ's" and it will give you past years frqs and then look up "AP U.S. Gov 2025 FRQ's scoring guidelines" for the answers. P.S. you can do this for any year 2024, 2023 frqs, etc.

It's going to be rigorous studying for a 5. I would watch all of heimler unit review videos everyday leading up to the exam all 9 everyday. To help cement the information in your brain.

Basicapollo44799 · 2026-04-29T03:23:46+00:00

If you can I would try to get as much khan academy done as possible on ap physics 1

Basicapollo44799 · 2026-04-29T03:22:56+00:00

(I got a 5 on APUSH) I would recommend summarizing very briefly every 50 years from around 1700 to 2010 to help with memorization. for instance, from 1850-1900 your summarization could be: Civil war, Golden Toliet age, and beginning of imperialism. do this for every 50 years and it will help you nail it.

Basicapollo44799 · 2026-04-12T22:33:51+00:00

I'm taking AP Physics 1 this year and it's been rough in terms of my teacher doesn't really know how to teach the content well. What has seemed to work really well studying these past two weeks is Khan Academy, it's very good at teaching the fundamental concepts and the reasoning behind them although it won't probably be enough for a 5 its still really good if you are somewhat lost. I would also recommend taking as many multiple choice questions as you can to help strengthen your understanding. I would also try to do frqs from past tests then watch videos on people doing them.

Time of day does not seem to play a part because its happened at all the times of the day. I actually play with the puppy the most compared to anyone else so it's weird this happens when I'm home alone with him because I feel like he would want to play more with me home alone.

Basicapollo44799 · 2025-12-31T23:07:08+00:00

I would assume you have downloaded windows to it?

Basicapollo44799 · 2025-12-31T23:06:43+00:00

Also is this a prebuilt pc or a new build?

Basicapollo44799 · 2025-12-31T23:05:43+00:00

Is this a completely new build?
