In the set of ordered pairs {(4,7), (4, -3), (-5, -9)}, the range is:

R = {-9, -3, 7}

Step-by-step explanation:

The range are all the outputs (y-values) in a given relation or function.

{(4,7), (4, -3), (-5, -9)}

The range in the given set is {-9, -3, 7}.

Hope this helps.

if x = 1, then the answer is 3.5

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
