I still don’t get why we gotta learn this 🤦‍♂️

[Lollypopxox]

Thank you so much my teacher thinks speed is more important than students actually getting the material. Im a slow learner this video helped me so much. Thank you so much.

[chelseamensah]

you are literally teaching me all my college classes rn. This channel is a god sent.

[mrnissan]

taking math 3 honors and god damn i thought my teacher was the only one that prioritized speed over explaining. definitely going to use this channel as my third source of information

[gummybacon]

3 hours of this in class i didn’t get it... 5 minutes of you and it’s like magic lmao

[nadialewis]

He teaches better than my college professor :, )

[jamesstriker]

my teacher just presents a picture of the lesson and expects us to know every problem. i went from getting C's on tests to 95+ because of your channel. thanks

[xgaq]

You are an absolute life saver. This makes so much more sense coming from this video than it did in my original lecture!!!! Amazing video!

[fishfan]

Lmao i had no clue it was that easy. Hands down one of the best tutorials for composite functions I got it within the first minute and a half

[fern]

Literally completely forgot all of this over the whole weekend, thank u for saving my life

[anayasheikh]

THIS MAKES SO MUCH MORE SENSE THAN WHEN MY TEACHER TAUGHT IT

For people wondering why we need to learn this, if you are considering to pursue a career in computing or some job with relation with programming, functions are extremely useful in this. Since functions can be used to create more advanced code. (And yes, it does get more difficult than this)

[donx]

You explain this so much easier than most professors! Word up!

[rhema]

Professor GENIUS. This person knows so much. I like the way he teaches maths. There was a topic I didn't understand in maths (finding the domain) but when I came here my solution came. He teaches more than my school maths teacher. He is the best. May GOD bless him abundantly!!

[divinityaustring]

I did not understand my lesson in Algebra 2 in my book until I watched this video. You explained this so well and clearly! Thank you for dedicating your time to help others. You have done me a great service! <3

[promaster_]

way better than what the school was trying to teach us online thank you so much!

[esme]

Bruh I can’t believe I have to teach myself. Online school ain’t it but thanks for this

[mackley]

This is one of those crazy math things I just love learning about. Confusing at first, but interesting and short enough to learn through quickly. Great video.

[alexandramirazizyan]

This was so easy to follow and I understood it quickly! I'm expecting to teach myself math next year (online school, ugh). Definitely giving you a follow. Thank you so much!

Badass! To follow-up for anyone still confused/not loving it, I did a longer 25 min video on functions, composite functions and domains, with test examples, on my Quant playlist if anyone thinks they may help to practice.
