Exercise 1 Page 24

Recall the function terminology.

domain, range, function

We want to fill in the blanks in the following sentence.

A relation that assigns to each element x from a set of inputs, of , exactly one element y in a set of outputs, of , is called a .

Recall that a relation where each input corresponds to exactly one output is called a function. This is exactly what the given sentence describes.

A relation that assigns to each element x from a set of inputs, of , exactly one element y in a set of outputs, of , is called a function.

The first and second blanks are asking for the terms used to describe a set of inputs and a set of outputs. These terms are none other than domain and range, respectively!

A relation that assigns to each element x from a set of inputs, of domain, exactly one element y in a set of outputs, of range, is called a function.
