and why...

Sure, you put in a value of x and get another value.
f(x) = 3x² / 4
f(0) = 0
f(1) = 3/4
f(2) = 3
f(3) = 27/4
etc.
A function is a relation that uniquely associates members of one set (the domain) with members of another set (the range). So if you put in a number for x, you always get a single specific value for f(x).

Yeah, because it's a many to one relationship. Something is a function if when you put a number as x you get a definate y.
This may seem odd but if you think about the inverse of that function you have an one to many relationship you get a positive or negative so it's not an inverse function.

yeah I think so, I believe a function is just where you get an output after you an input. Like x = your input, and the output is the answer after you square it and take it times 3 and all that
