Functions
A function is a relationship in which there is exactly one output value for each input value. The functions used in algebra incorporate all sorts of operations — from addition and subtraction to absolute value and factorial. Functions might be restricted as to their input values; the input values constitute the domain. And a function may have a limited number of output values (its range) due to the way the operations are performed on the input values.
The Problems You’ll Work On
In this chapter, you’ll work with functions in the following ways:
