Answer
The set of ordered pairs represents a function.
Domain: $\left\{-2,-1,3,4\right\}$
Range: $\left\{3, 5,7,12\right\}$
Work Step by Step
According to the definition of a function, one first element must be paired with exactly one value from the second set.
In this case, this is true for all pairs.
The domain contains all values from the first set of the function:
Domain: $\left\{-2,-1,3,4\right\}$
The range contains every single value from the second set that are paired with elements from the first set:
Range: $\left\{3, 5, 7,12\right\}$
