Answer

The domain consists of all the x-coordinates of the ordered pairs: $\{5,10,15,20\}$ The range consists of all the y-coordinates of the ordered pairs: $\{20,30\}$.

Work Step by Step

The domain consists of all the x-coordinates of the ordered pairs: $\{5,10,15,20\}$ The range consists of all the y-coordinates of the ordered pairs: $\{20,30\}$. The relation is graphed by plotting all the given ordered pairs as points. A mapping diagram shows (with arrows) which output(s) are associated with the inputs.
