i think its a. but i'm honestly not 100 % sure.

anonymous · Answer

So your question in mathematical language translates to -


Mapping notation showing 3 4 and 9 in the x oval and negative 1 negative 5 6 2 and 7 in the y oval. There are arrows pointing from 3 to negative 1 from 3 to negative 5 from 3 to 2 from 4 to 7 and from 9 to 6.

(3,-1), (3,-5) , (3,2), (4,7), (9,6)

Hence one domain has many solutions in the range which is not possible.

every element of x oval has unique solution in y oval; so x oval cannot have 2 solutions however an element of y oval can be a single solution of 2 or more elements in x oval.

ans - B. not a function.
