Chapter 2 - Functions and Graphs - Exercise Set 2.1 - Page 224: 3


The relation is not a function. Domain: 3, 4; Range: 4, 5.

Work Step by Step

Since there is not only one $y$ for each $x$, the relation is not a function. The Domain is the set of all $x$'s, or what "you start with". The Range is the set of all $y$'s, or what "you end up with", after each member of the Domain has been changed by the function.
