Each set of orther pairs (x, y) represents a relashionship with imput, x, and output, y. which relatonship is a function? a. {(0,1), (0,2), (0,3)} b. {(1,1), (2,2), (3,3)} c. {(1,1),(2,1),(3,1)} d. {(1,1),(2,2),(2,-2)} e. {(1,-1),(2,-2).(3,-3)}

  b, c, e

Step-by-step explanation:

A function has unique x-values (inputs). Several of the relations here are functions:

a. {(0,1), (0,2), (0,3)}  . . .  repeated x-value of 0, not a function

b. {(1,1), (2,2), (3,3)}  ... function

c. {(1,1),(2,1),(3,1)}  ... function

d. {(1,1),(2,2),(2,-2)}  . . .  repeated x-value of 2, not a function

e. {(1,-1),(2,-2).(3,-3)}  ... function
