Answer:

  yes, it is a function

  domain: {-8, 2 ,4, 5, 6}

  range: {-6, -4, -2}

Step-by-step explanation:

The domain is the set of first values of the ordered pairs: {2, 6, 4, 5, -8}. We often like to see them in order:

  domain: {-8, 2 ,4, 5, 6}

The range is the set of second values of the ordered pairs.

  range: {-6, -4, -2}

There are no repeated values in the domain, so the relation is a function.
