Question #8dc15

Answer 1

The points do represent a function.
The domain is the set: `{-34, 19, 27, 45, 53}`.
The range is the set: `{-14, 2, 8, 63, 67}`.

Explanation:

When presented this way, the domain element is the first value in the ordered pair and the range element is the second value in the ordered pair. So it looks like: (domain, range).

We have:
`{(19,2), (45,8), (-34,63), (27,-14), (53,67)}`

So just listing elements we have:
domain elements are `19, 45, -34, 27`, and `53`.
range elements are `2,8,63,-14,` and `67`.

Since none of the `x`-values is associated with more than one `y`-value, the points do represent a function.

So the domain is the set: `{-34, 19, 27, 45, 53}`.
The range is the set: `{-14, 2, 8, 63, 67}`.
