Question

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

Answer 1

domain = first elements ={4,5,6,7,8}

and range = second elements {2,1,2,3,6}={2,1,3,6}
2 repeated

Answer 2

\(\bf f = \{(4, {\color{blue}{ 2}}),(5, {\color{blue}{ 1}}),(6, {\color{blue}{ 2}}),(7, {\color{blue}{ 3}}),(8, {\color{blue}{ 6}})\}\qquad {\color{blue}{ range}}\)

Answer 3

for an ordered pair set, the range is always the "y" coordinate value
