If A and B are sets of numbers a function
f: A -> B is a rule which assigns to each element of x in A a unique element f(x) in B.The set A is called the domain of f. When not given explicitly the domain of f is the largest set of numbers for which the rule makes sense
Example:
( )
If f is a function the zeroes or roots of f are all of the elements r in its domain such that f ( r ) = 0
Alternatively the roots of f are all solutions to the equation f(x) = 0
