Functions - Vertical Line Test, Ordered Pairs, Tables, Domain and Range

This math video focuses on functions. It explains how to tell if a relation is a function given a set of ordered pairs or a data table. In addition, it explains how to use the vertical line test to determine if a graph or curve is a function based on if it touches the line at two or more points. Finally, this video discusses the domain and range of functions briefly.

"Are the videos from 2006 really helping?"
Yes, even though this channel started in 2017, IT HELPS SO MUCH. This 10 min video did something my math teacher could not do in 1 hour.

[zeinashreif]

Ur the best teacher ever, I always learn more from u not from my classroom teacher, thanks soooo much for ur good explanation and ur time as well

[twosongs]

I love your voice, it’s calming and helping me review a few things. Thank you👍🧸

[ayeharuna]

I really don't know what to say. Thank you so much sir for such a heart of love that make you tutor in such a simplified form. God bless you richly.

[mqadi]

This channel should be a university...evrything is expalained CLEARLY thank you verymuch

[NotShreksWife]

As someone who is basically an average human when it comes to mathematics, this video helped me a lot😁 Thank you:)

I've always said, and I will maintain, that the only relevant setting of knowledge after 2005 is the laboratory (2005 is the creation of YouTube and Vimeo and the start of a full online and social media age). Most classrooms are not worth it anymore because most teachers are not teachers, they are simply professionals with no passion at all to impart their knowledge. The Organic Chemistry Tutor is a teacher...he knows the stuff and can impart it clearly. We need more of him in schools all around the world, even in developed countries (I've been to 6 of them and very many of their teachers suck even though they have all the facilities and equipment). Keep up your good work and the earlier UNESCO realizes this the better.

I love your videos! You explanations are way simpler than other videos.

[KhabbuKiKitchen]

Really amazing videos but i do have a little suggestion..it would be great if you could make different playlists for different chapters. It would make it so much easier for students. Thanks!

I'm about to be a college sophomore the fall this year, & I have to take a precalculus course in order for me to graduate college on time during my senior year. I'm just looking through your videos just to get a little review in before I move in & start the class. This was actually pretty helpful ngl. Thank you :)

[chocolatee]

If I'm gonna be one of the greatest mathematician of this era, I will not forget you. You are my master and I'm gonna flex you FOR R.E.A.L.

For some reason our pre-calc curriculum doesn't cover some parts of topics so I don't understand anything but when I watch your videos because you don't exclude anything so I easily understand why something is the way it is.

[meamayloveme]

I am a student just starting a new class precalculus Bridge, im just wanting to know if this whole video list is in order because my teacher sucks and im going to teach my self as much as i can but i dont want to get cofused with what to watch first.? P.S love your math videos they help me out alot 👍

[nicolasoliveira]

Thank you so much for making this helpfull videos. I learned a lot with your videos !

[jenmarie]

Thank you, you have no idea how much you are appreciated!

[cwprq]

I'm gonna start watching your videos seriously from now on

[MaziraJocelyn-bpqr]

You always make me understand what l have not understood in the lecture room. May you continue with the spirit

[isaacyarh]

Thanks so much, your videos are all educative! And helpful to many students around the world. Thank you once again.

[magske]

My deepest regret is discovering this channel while on the verge of finishing campus. I'll never forgive myself.

[fatoukanyi]

You are the best tutor. Thank you for your lessons.
