Functions are another way of describing certain things mathematically. There is a special type of algebraic+relations+ called a Function.
An algebraic relation is a set of ordered pairs, like (2,4) (3,6) (4,8) (5, 10).
The domain is: 2, 3, 4, 5 (These are all the x values of the ordered pair)
The range is: 4, 6, 8, 10 (These are all the y values of the ordered pair)
The domain contains the independent+variable and the range contains the dependent+variable. This means that the value of the range depends on the domain.
Think about the vending machine: What comes out of the machine (range) depends on what you put in (domain). You can't put in a nickel and expect a chocolate bar to pop out!
So. in your case a=%281%2F4%29f, this is a function where the domain is all values of f and the range is all values of a. The f is the independent+variable and the a is the dependent+variable.
