Afunction is represented by the set of ordered pairs shown below. {(-4,3), (-1,3), (0,3), (1,5), (3,7)} what is the range of this function

{3, 5, 7}




The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input. The output values are y = 3, y = 3, y = 3, y = 5, y = 7. So we simply list these outputs without the "y=" portion. Toss out any duplicates. Only write the unique output values. 

The curly braces surrounding the list of values tells us that we have a set. 

There is no association.
