A function is a rule that assigns to each number in its domain one number in its range. It is expressed in the form
where f and x can be replaced by any letters.
A function is a special type of relation where each x value has only one possible y-value.
For example, f(x)=3x2−2 is a function, but x2+y2=1 is not, since y=±√1−x2 has two possible values for each x.
