Question 1044767: For the set {(0,1), (-3, 7), (4, 6), (5, 0), (4,8)},
a. State the domain.
b. State the range.
c. Is this relation a function? Why or why not?
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! 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.
