Thank you for all of you videos. My pre-cal teacher in HS only passed 3 kids in my class ( he was a really bad teacher). Now I'm having to take it again 20 years later. You're a lifesaver.

Starting this video at 1 am the night before my test!

[mikemendez]

i love you, my finals in half an hour

Thanks man, big help for studying. Just watching what to do and seeing any potential mistakes i’d make is all the help i think i’m going to need. I understand and get most of it, just a lot of info is being crammed into 25 questions for a final (my final) will get all my info mixed up in my head, hopefully this clarifies some stuff

[FunFactopias-Facts]

Mine is in 5 days. I will let you know how it goes. So far practice is doing great!!
Wouldn’t have passed the first two quarters without you ❤

Excellent job in explaining question 48. Haven't seen this type of question before.

[nathaliejewell]

literal life saver. this is definitely going to help me on my final

[peeeet]

Thank you so much as a highschool sophomore preparing for the test. Spent 3 days Watched the whole thing and actually been working those problems.

I’m loving this channel so far but I wish there were major playlists like ones for alg1 and alg2 and so on for easier organization. It would help if each of them had a label too. Also, I don’t know what the ADD stands for in the title of the playlists? I am looking forward too watching more

[aleckbo]

Thank you so much for everything so far. You’ve helped me a lot.

Thank you Mr. McLogan for all u have done for preCal

For problem #23 you did alot of unneeded work. You could have left the equation in the factored form and just put the k in front of it and then plugged in the (-1, -52 point) to solve for k. It doesn't matter what form polynomial was in(factored or standard) to solve for k.

Holy shit, 4 hour long video, my man is a SAINT.

[chrishansen]

thank you so much for this and especially for the time stamps in the description box

For problem #8, wouldn't the answer be A? You're shifting FIRST then reflecting, so you should be multiplying f(x)+4 by -1, getting -f(x)-4

[awesomecodeyay]

Hold on
Isn’t number 13 b? Because, for example, if I plugged in -3, I’d get
sqrt((-3)^2), which is 3, not -3
If it was d, then it would look like this
Sqrt((-3)^2)=-3, which is not true, so it should be absolute value of x

I have pre-cal in two years... this looks not too bad for a final.

[lasyabharadwajgurugubelli]

Sir you are the best! U are literally saving the students life love u! Seriously love u sir! No homo! Genius!

[redwoodenjoyer]

For number 8 it should be A, right? By reflecting over the x everything is multiplied by -1

[ryanwilson]

Question 8 is wrong!
You got the shifting and reflecting of f(x) in the wrong order according to how the problem is worded.

It says to shift the graph y=f(x) up 4 units FIRST and then reflect the graph across the x-axis SECOND.

The end result should be y= -f(x)-4.

Starting with y=f(x)…

Shifting up 4 units results in y=f(x)+4


Reflecting across the x-axis results in y= -[f(x)+4]= -f(x)-4, where the negative sign gets distributed.
