A. {(2,3),(2,6),(2,9),(2, 12), (2, 15)}
B. {(2,6).(-3,6).(-8,11), (6,2) (9,-7)}
C. {(3,-5),(4, -4),(5,-3),(4,-2),(3,-1)}
O D. {(3,8).(-3,2),(-6,0),(-3,-2),(3,-8)}
Help me please
A. Is not a function, the x value 2 has many outputs B. It is a function, all the x values have different outputs C. Not a function, the x values 3 and 4 have different outputs D. Not a function, the x values 3 and -3 have different outputs
A relation is a function if each input value (or x) has only one output. However, the outputs could have many inputs.
