domain = $\left\{3, 4, 10\right\}$ range = $\left\{5, 9, 13\right\}$
The domain is the set that contains the values first coordinates (the dependent variable), while the range is the set of values of the second coordinates (the independent variable). Thus, the given relation has: domain = $\left\{3, 4, 10\right\}$ range = $\left\{5, 9, 13\right\}$
