Because of this guy I realized that math isn't hard to understand, but our university professors make it critical and hard to understand.

The Organic Chemistry Tutor has been helping students for years, and years to come. Deserves so much gratitude.

Absolutely phenomenal video. I got behind in math and completely missed out on the finding the domain and range stuff. The textbook we have explains it in such a complex and brief way that its impossible to understand anything. Thank you so much for helping!!!

[lavendertiles]

man these comments. i’m lucky enough to have a good math teacher, just stayed home today so i needed this

[isaahmed]

U are the best teacher in the world continue this🙏

[MsHortel]

Thank you. I was so lost an hour ago. Now I get it. I prayed to St Joseph Cupertino for help then I went to youtube and found your video again. Because of you I got 92% on my first exam. I missed the simplest question bcoz I was panicking.

thanks for that good video It helped me understand it thank you so much!

[SuperZinc-]

How much time does it take you to make each video (ish)? Would love to know! Amazing video btw

Hi Organic Chemistry Tutor, I was wondering if what apps do you use for solving the things and editing your voice with the video while solving :>

[eshmaelashiqui]

I am a winner to be part of this wonderful channel....thanks.❤💯

[saturnsglaive]

I swear to God if I have know about this in my algebra/precalculus module next week then I have been bless with timing on this video 😭🙏🏻

[beautermanesser]

🥺🥺 good work, you have helped me so much

[Yo-ue]

Oh my lord we needed this topic thanks sensei

[ggg]

Please confirm this, does domain remain "all real numbers" for any quadratic function?

[hereast]

thank you!! we were going over this in class

[lindseylediamond]

So you just write negative infinity to infinity the way you do without writing any specific x values?

5:10 "The vertex is gonna be at" *ad break*

[Ashystar]

Wish I'd had this during pre-calc 😅☀️

How did you get the 2 for the x coordinate of the vertex

[davinci]

8:03 how did x become 2 on the vertex
