Question 1044767
a) The domain is the set of x coordinates. So the domain is {0, -3, 4, 5}. Notice how I only list each unique x coordinate once.

b) The range is the set of possible y values. So the range would be {1, 7, 6, 0, 8}


The order doesn't matter since sets can be written in any order. If you wish, you can order the values from smallest to largest


----------------------------------------------------------------------


c) This relation is NOT a function because (4,6) and (4,8) have the same x coordinate of x = 4 but different y values of y = 6 and y = 8. A function is only possible if every x value is associated with EXACTLY ONE y value only.
