WOW. GOOD EXPLANATION RIGHT THERE.
-
I am studying alone, and these video are very helpful for me. Thanks indeed.

f(x) means Y

You've taught me more than I've learned in class today.

This is a good explanation.
I think kids should be introduced to multivariable functions as early as possible so I thought you did that well.
Although, one thing you left out that I think is important is that just because x and y are in the function, that doesnt mean you have to lable it f(x,y), x or y could be a constant or variable-constant and in that case you would just call it just f(x) or f(y).

I always associated the letter "f" with the word "function" (which I assume is why it is used.) So instead of saying "'f' of 'x' equals..." you say "the function of (variable) 'x' equals..." Obviously you can still use anything else in it's place; this just helped me when I was learning.
