# Chapter 3 - Section 3.2 - Introduction to Functions - Exercise Set: 7

Domain: {0, $\frac{3}{2}$}, Range: {-7, $\frac{1}{2}$, $\frac{4}{5}$}, No

#### Work Step by Step

The domain is the set of all first components of the ordered pairs, or {0, $\frac{3}{2}$}. The range is the set of all second components of the ordered pairs, or {-7, $\frac{1}{2}$, $\frac{4}{5}$}. This relation is not a function because $x=\frac{3}{2}=1\frac{1}{2}$ corresponds to more than one component in the range.
