Number (x)| 8 | 27 | 64 | 125
-------------------------------
Cube root (y)| 2 | 3 | 4 | 5

Answer 1

Does the table represent y as a function of x? Justify your answer.

Answer 2

look at your points..
(8,2) (27,3) (64,4) (125,5)

A function cannot have 2 x values that are the same. A function can have 2 y values the same, but not the same x values. Do any of your points have the same x value ?
