Relations & Functions 

This dude is still giving hearts 9 year later what a legend

*The video really helped me. Am 20 and I feel so ashamed of not finishing hs sooner, so having effective youtube videos is a big help. Also, it reduces the stigma of asking for help, and the anxiety of other people watching me fail. Thank you!*

When you realize this is much more easy to understand than your textbook

You're very welcome to make use of my videos! I hope they're helpful! :-)

took 7 MINS and helped me understand it so well so easily. YOU ARE A LEGEND sir, thank you

Thanks man you should of been the one to write my text book.

I paid $250 for a college book to explain this to me and yet I had to learn this from a youtube video. Thank you so much Mr. Marty Brandl for making it all make sense to me.

Thank you so much, I was literally staring at my math homework for at least 30mins just clueless and none of my friends were available to help me. Because of you I got my math homework turned in on time!

*actual teaches me when my teacher and textbook are useless*

So helpful!! You've been the only one able to explain what I didn't understand. Whew!! Finally. :)

my god u actually explained it.You did what the title said.IT couldn't be simpler but alot of videos are having extreme trouble explaining this for some reason.Difference between saying what you know and teaching someone.good work

You passed because of your work! You can do anything you put your mind to! :-)

This man shall never be forgotten, because he, he helped me in my task and test, He is A Legend!

As the saying goes, "Don't repeat your ex's" as in x

thNks man i watched this because i want to be advance on k11 math. My prof was happy because i able to answer this on my pre-test and i got the highest score thanks man 😊👍

There's always that one hidden math teacher who explains it flawlessly!

With e learning I never understood this and I'm in the middle of a test in the first 50 seconds of watching I understood. I truly can't express my gratitude

You helped me alot sir, thank you! My teacher discussed this for an hour and in just 7mins you made it clearer than what my teacher can do.

One of the only guys who cuts the crap out and gives you what you need

thank you very much.. I have math final test tomorrow, and I was really confused in this lesson.. but now I feel that this lesson is the easiest. thank you very much.. and always be my digital teacher😆☺😄

I searched many videos on functions but they all failed to teach easily. You explained very well.

You just described the hour and a half amount of info that my teacher made impossible to understand very easily and understandable in 7 and a half minutes, thank you.

This helped soooo much

FINALLY! SOMEONE WHO IS VERY SPECIFIC ON BOTH FUNCTIONS AN NON FUNCTIONS! NOT JUST ONE FUNCTION AND THEY END THE VIDEO THERE AND NOT MAKE AN EXAMPLE ON THE OTHER! THANK YOU SIR!!😁

I was absent for a few weeks for personal reasons and this explained some of the lessons we learned in an easy, simple and understandable way. I love this so much, thank you! If only I could have you as a tutor haha.

Thanks! :-) I have quite a selection on algebra topics. Is there something specific you're looking for?

I know that this video was posted a few yrs back but I want to say thank you thank you soooo much this have helped my daughter tremendously she was about to fail a test so I googled , searched you tube all over and other videos are just so confusing , you explained everything so well .. I have no clue when it comes to helping my daughter with her homework so this video definitely helped us out both .i learned something new as well .. thank you I appreciate the time you took to make this video 👍
