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
