# What is the domain and range of ( (7.6, -0.2), (8.8, -0.2), (2.3, -4.6) )?

Domain : $\left\{2.3 , 7.6 , 8.8\right\}$
Range : $\left\{- 0.2 , - 4.6\right\}$
The domain is the set of all first elements of ordered pairs (x-coordinates): $\left\{2.3 , 7.6 , 8.8\right\}$
The range is the set of all second elements of ordered pairs (y-coordinates): $\left\{- 0.2 , - 4.6\right\}$
