Question

What is the Range of the relation?

{ (2, -1), (3, 1), (4, 2), (5, 8) }

Question 3 options:

{-1, 1, 2, 8}


{2, 3, 4, 5}


{1, 1, 2, 8}


{-1, 1, 4, 8}

Answer 1

The answer is the first one. I'll just add that if you run into this type of problem again, an easy way of finding the Range in a relation is to find whatever y-coordinates. For example, (2,-1) x=2 y=-1 so -1 would be the first range number. Hope this made sense!

Answer 2

the answer is, {1, 1, 2, 8}
