Within 3 minutes watching this video, i felt like i could pass any test. Within 30 minutes of my teacher trying to explain this in class, i was clueless. Really appreciate what you're doing!!

[Andrew-izev]

I'm supposed to be taking notes from my teacher, but instead I am taking notes on these videos because your explanations are way better :')

[ekscorels]

The "what would you say" at 9:54 made me feel so welcomed and warm inside🥺
You are an amazing teacher

[Andrew-izev]

I need a part 2 video for how to find the range of a function that has fractions, fractions with quadratics in them, and fractions with radicals in them

[walaa]

when I hear your voice I become sure that I will understand, love you thanks <3

[TheXxSPANKERxX]

Such a relaxing and reassuring voice.
These are truly the golden ages.

[kawtharhathroubi]

you saved my life bro, there was something I couldn't understand and I looked everywhere for it and couldn't find it and you explained it so clearly. thank you!!!

[graciekinnaman]

Thank you. You explained this quicker and better than my algebra II teacher did today.

[toshi_eve]

You explain just the way my teacher does, he is old enough, so we don't understand what he is tryna saying. But after watching this, I understood he is teaching us in a correct way, and noone is at fault.

[ibtesammirza]

I'm terrible at math and I find it hard to understand, but this video was super easy to understand, so thank you so much for your help.

[faithchidogarikayi]

Its my first time attending your tutorial and wowww l am just surprised at how you make difficult things look easy

[lyndseystrait]

Whenever the leading term has an odd power, the range will be either - infinity to infinity or vice versa. Whenever the leading term has an even power, the range won't be negative infinity to infinity but instead be limited (by transformations, etc). If is a quadratic expression w/ even leading power, may have to solve for the vertex by using the formula -b/2a to find x & then plug that value in to solve for y. 7:11 Absolute value functions transformations with corresponding ranges. 9:12 Radical function ranges & graphs (sign outside of radical & inside by x determine which quadrant line will be in). 10:09 For transformed radical function.

You are single-handly keeping my A in College Algebra. thank you

MR. Organic Chemistry Tutor, thank you for graphing and showing How To find the Range of a Function.

[myredditanecdotes]

I'm studying in of the best high schools in my country but this man explains the topic we're learning better than our teacher.

[juniemoe]

Your explanation is so clear to memorize, I got lucky that I watched your video before a few hours of my final exam which I was struggling to finding a range, domain and graphing in most Thank you so much...

[okotray]

So helpful, lots of content covered within the shortest time possible. Thank you so much

[sebastian]

Everything is on point.
You make things so easy to understand

[mwilamolobeka]

So helpful. Finding it useful as a student

[mariamsamy]

You are one of the reason to get 700+ on math thank u soo muchhhh❤❤
