The graph below displays the wrist circumferences and heights of six students in Alyssa’s classroom. A graph titled Wrist Circumference versus Height has wrist circumference (centimeters) on the x-axis and height (centimeters) on the y-axis. Points are at (13.8, 151), (14.2, 151), (15.2, 156), (15.6, 159), (16, 162) and (16, 165).

Is the height of these students a function of their wrist circumference?
Yes because as wrist circumference increases height also increases.
Yes because a line can be fit to these data to predict other pairings.
No, because the height of 151 cm is paired with two wrist circumferences.
No, because the wrist circumference of 16 cm is paired with two heights.
