THANK YOU SO MUCH!!!! You explained everything so clear...math has been so traumatizing to me till this day....I never had good math teachers....I actually understood thank you lol

[Eristhenes]

Thank you. I had this in pre-algebra in college (cause I failed the basic math test) and had such a difficult time understanding it. You do a great job of making functions understandable.

It is not simply points it is exactly one output for each input. By connecting all the points you are provided a graphical overview of the function.

[kornkocel]

a function is a rule that operates on an input/argument to produce a single output

[Henchetarian]

This is the best video I've seen online explaining functions, thank you!

Short, simple and correct! Well done!

I wish our distance education instructor would teach like this. There is something more authentic about handwritten visual then ones that are typed. I also like the fact that this lecturer doesn't get sidetracked or joke around. The instructional videos on MyMathLab (which our college forces us to purchase access to for $100+ in addition to tuition) is worthless compared to this. Thanks!

[carlosvalentin]
