The domain of the relation is the set of all the first elements in each ordered pair, which are the names of the planets: {Venus, Mars, Jupiter, Saturn, Neptune, Pluto}.
The range of the relation is the set of all the second elements in each ordered pair, which are the given numbers: {14, 16, 46, 14, 37}.
To determine whether the relation is a function, we must check if there are any repeated first elements (planets) with different second elements (numbers).
In this case, both Mars and Jupiter have the same second element (16), which means that the relation is not a function.
Therefore, the answer is: None of the above.
Find the domain and the range of the following relation. Also determine whether the relation is a function.
Venus 14
Mars 16
Jupiter 16
Saturn 46
Neptune 14
Pluto 37
Is the relation a function?
O 14 to 46
O {14, 16, 46, 37}
O (Venus, Mars, Jupiter, Saturn, Neptune, Pluto) O None of the above
