Answer:

(B) {(2,1),(4,3),(5,7)}

Step-by-step explanation:

If the same x value goes to 2 different y values, it is not a function

(A) {(2,3),(2,5),(4,7)}   the x value 2 goes to 3 and 5

(B) {(2,1),(4,3),(5,7)}

(C) {(3,-2),(2,4),(3,6)}  3 goes to -2 and 6

(D) {(-1,4),(-1,5),(2,5)}​-1 goes to 4 and 5
