Question

Which set represents the range of the function shown?

{(−1, 5), (2, 8), (5, 3), (13, −4)}

{−1, 2, 5, 13}
{−4, 3, 5, 8}
{(5, −1), (8, 2), (3, 5), (−4, 13)}
{−4, −1, 2, 3, 5, 5, 8, 13}

Answer 1

isnt it
{−4, −1, 2, 3, 5, 5, 8, 13} ??

Answer 2

keep in mind it's asking for range, so y-values only

look inside each set of parentheses and take the y-coordinate only. should only end up with 4 data points

Answer 3

so its {−4, 3, 5, 8} right?

Answer 4

yup

Answer 5

thank you!
