Question

Determine if each set of ordered pairs represents a function.
(2,3), (6,-5), (-1,3)

Answer 1

yes

Explanation:

You can perform the "line test." If it is a function, there will not be two x's of the same value. In this case, x is 2,6,-1. No number repeats, thus making a function.

Answer 2

Function:

(7, -4) (0, 9), (2, -2)

(-6, 5), (-5,6), (8,2)

(2, 3), (6, -5), (-1,3)

Not a Function:

(1, 9), (-3, -2), (1, -4)

(0, 3), (0, 7), (4, 0)
