6) Which relation describes a function? A) {(0, 0), (0, 2), (2, 0), (2, 2)} B) {(−2, −3), (−3, −2), (2, 3), (3, 2)} C) {(2, −1), (2, 1), (3, −1), (3, 1)} D) {(2, 2), (2, 3), (3, 2), (3, 3)}

B) {(−2, −3), (−3, −2), (2, 3), (3, 2)}

Step-by-step explanation:

B) {(−2, −3), (−3, −2), (2, 3), (3, 2)}

each input of x (-2), (-3), (2), (3) does not have duplicated output value

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
