Never heard that one before, any reason?

@maximuminsight1 You're saving me, a student terrible at pre calc, so you need a million dollars as payment for your efforts

You can, of course, do that! Since the question kept saying 76 thousand and 40 thousand, I decided it would be easier for me to work with the lower numbers. But yes, doing it like "76,000-40,000/91" and getting 396 games per day is perfectly acceptable.

Apologies, I mistyped that question and accidentally made it have two correct answers, I blurred out the answer choice A in the youtube editor so others don't get confused. Thanks for pointing it out!

@@maximuminsight1 No problem! Thanks for saving my grade by the way 😆

Will do!

Are you high dude? He literally explains each topic so easily and minimally. This is the best AP Precalc review I’ve found. If you can’t understand it, it’s a problem with you 😂😂.

You are correct, I appreciate the help. These videos are made fast and sometimes little things like these slip through the cracks, I appreciate all help to maintain the validity of my videos and will fix this mistake with the KZbin editor.

The reason you change the 2 to 2.001 is because you are finding the rate of change between two points right next to one another. This makes 2 the X1 and 2.001 the X2 in the rate of change formula.

@@maximuminsight1Thank you!

I really like these vids very informative :D

The unit 2 review will be posted once all the unit 2 topic videos are finished. I’m going to try my best to edit and produce them within the next week.

Thank you! I’m not even joking, the only reason that I’m understanding my AP Precalculus class so far and passing it is bc of you. You explain everything so clearly and in a simple way. After watching your review video for unit 1, I got a 90 on my unit 1 test. Thank you!

That question is a little misleading, I only provided a little portion of the graph and not the full thing so it’s hard to say from what I provided that there are three points of inflection. The only reason I said it was 3 was because I had access to a more complete graph where I could see that the concavity obviously changed at the points (-4,2) and (2,2), so don’t feel bad about not getting all three, that ones on me. However, the concavity of the graph does change at the point (-1,2) and not (0,0) therefore making (-1,2) the point of inflection. Think of it this way: Concave down is like an umbrella such that if you poured water on it, the water would come spilling off. Concave up is like a bucket because if you poured water on it, the water would collect. Or what I said in my topic 1.1 video, concave up is a U and concave down is and upside down U. Look for when it changes and that will be your point of inflection. Hope this helps!

Can’t argue with that, my videos are designed in a more “quick review” format though.

although isn't the global minimum supposed to be none, as the graph infinitely decreases? i reckon there may be a mistake

@@umarthethird You bring up a solid point. Global/Absolute maximums don't exist if the graph goes to positive infinity and vice versa when going to negative infinity. The example graph I used in the video made it seem as if the local maximum was a global maximum despite the graph going to infinity. I apologize for not making that clear and will try to use the KZbin editor to fix that error (likely by blurring it out). I appreciate any comments helping me maintain the validity of the videos I make, these videos are made fast and mostly accurate, sometimes little things like these slip through the cracks and I appreciate you for pointing it out.

That's what I'm here for, make sure to come back around during unit 2.

@@maximuminsight1 thanks

Hey, thanks for pointing that out. I reviewed the video and have fixed the error. Thank you so much for telling me and helping me ensure the validity of the videos I make!
