Which functions on (5, 6, 7, 8) × {w, e, r, t} is one to one?
O {(5, r), (6, w), (7, e), (8, e)}
O {(5, r). (6, w). (7, e), (8. r)}
O {(5, r), (6, r), (7, r). (8, r)}
O {(5, e). (6, t), (7, r), (8, w)}
QUESTION 8
Which of the following relations describes a function?
O g from R to R g = { (2, 2). (3, 2). (4. 2), (5, 2) }
o g from R to R g ={(-2. 0), (0. -2). (0. 2), (2, 0)}
O g from R to R g = { (0 0), (2. -2). (2. 2), (3 3)}
g from R to R g = ((2. 3) (2, 4). (2, 5) (2. 6) }
