identify the TWO sets of ordered pairs that represent a function
A).(1,-1),(-2,-7),(0,1),(-1,-1)
B).(1,-3),(-2,-8),(0,-1),(1,-2)
C).(2,-3),(-3,6),(-2,-2),(2,3)
D).(-3,2),(1,6),(2,2),(1,3)
E).(-5,2),(2,6),(3,2),(4,-5)
(1, −1), (−2, −7), (0, 1), (−1, −1) and (−5, 2), (2, 6), (3, 2), (4, −5) are functions because each x value corresponds to exactly one y value. a function must have only one output value for each input value.
