Question

Which set of ordered pairs represents y as a function of x?O {(3, 3), (3,4), (4,3), (4,4)}O {(2, -1), (4, -2), (6,-3), (8, -4)}|O {(0,0), (1, 1), (1, 0), (2, 1)}o {(1, -5), (1,5), (2, -10), (2, -15)

Answer 1

Second choice from the top.

Explanation.

An ordered pair will be considered a function if no two different values of y are given by the same value of x.

For example, a set of ordered pairs constaining (4, 3) and (4, 8) would not be considered a function.

Looking at the choices given we see that only the second choice in the couln gives
