For the set of ordered pairs, state the domain, range, and determine whether or not the relation represents a function.
(9,9), (7,4), (1,2), (2,6), (5,0)
Domain: 9,7,1,2,5
Range: 9, r, 2, 6, 0
It is a function because no x value is repeated
if r = 4 than you got this answer correct. Congrats.
To determine the domain of a set of ordered pairs, you need to identify all the unique x-values in the set. In this case, the x-values are 9, 7, 1, 2, and 5.
To determine the range of a set of ordered pairs, you need to identify all the unique y-values in the set. In this case, the y-values are 9, 4, 2, 6, and 0.
Therefore, the domain of the given set of ordered pairs is {9, 7, 1, 2, 5} and the range is {9, 4, 2, 6, 0}.
To determine if the relation represents a function, you need to check if there are any repeated x-values. If there are no repeated x-values, then the relation is a function. In this case, there are no repeated x-values, so the relation does represent a function.
