Question

If ƒ={(5, 1),(6, 2),(7, 3),(8, 1),(9, 7)}, then the range of ƒ is

Answer 1

1,2,3,7
I believe the range is just depending on your y values,and since an equation is not given your range should just be the y values of that set

Answer 2

I think this should help :-)

1. The points that are in given in the (x, y) form aka (x-coordinate, y-coordinate).

2. The range is the set of values onto which ƒ sends the x's.

The x's are sent the numbers 1, 2, 3, 1, 7 which ends up looking like {1,2, 3, 7}

So the answer is {1,2,3,7}
