Answer:

  D = {5, 6, 7, 8}; R = {-3, -2, 0, 10}; is a function

Step-by-step explanation:

The domain is the list of x-values. The range is the list of y-values. We often like to see these lists in order smallest to largest.

If there are no repeated x-values, then the relation is a function.

  D = {5, 6, 7, 8}

  R = {-3, -2, 0, 10}

  Function? yes
