Question

What is the range of the function: {(2, 1); (4, 2); (6, 3); (8, 4)}?

{1, 2, 3, 4}

{2, 4, 6, 8}

{1, 2, 3, 4, 6, 8}

{6, 8}

Answer 1

range describes all the y values available. in this case, you're given a set of numbers, so all the y values given is your range. This can be described with the y value of each point : {1,2,3,4} hope that helps! :)
