Question

If ƒ = {(4, 2),(5, 1),(6, 2),(7, 3),(8, 6)}, then the range of ƒ is


{(2, 4),(1, 5),(2, 6),(3, 7),(6, 8)}
{1, 2, 3, 6}
{4, 5, 6, 7, 8}

Answer 1

u can find the range of f by making the set of all the values which appear after ' , ' in the pair.

Answer 2

so picking all the 2nd values
2,1,2,3,6
so the set is
{1,2,3,6}
ok?
