Answer 2

The only table that can represent y as a function of x is;

Option D

Table A; For this table to represent y as a function of x, then it means that a

value of x cannot produce two different values of y and vice versa. Yet we

see that x = 2/5 produces 2 different values of y which are y = 10 and y = 7. Thus, this table can't work.

Table B; We see that when y = 17, we have 2 different values of x which are

x = 1/6 and x = 1/2. Like stated for table A, this table can't work.

Table C; We see that when x = 20, it produces 2 different values of y which

are y = 345 and y = 355. Like stated for table A this table can't work.

Table D; We see that each value of x produces a distinct value of y and as

such this table can represent y as a function of x.
