The definition of a function is a transformation that maps a set of x-values to a set of y-values (or inputs to outputs). The x- and y-values do not necessarily have to be real numbers; they could be complex numbers, or vectors in any number of dimensions.

For now, you can define a function f(x) = ... For example, f(x) = x+2 is a function; so is f(x) = floor(x) (floor value of x).
