Answer 3

I'm terrible at math, especially graphs, but I tried to think it through and I got that B is correct..I highly doubt it though

Answer 4

for these problems, try and think as relation between father and son.
take x as son and y as father.
so for a relation to be a function
Remember this:
1:A father can have more than one child.(y can be linked with more than one x)
2:But a child can not be there wihout a father.( x should not be there without any y linkage).
3:A child can't have more than one father( x should not be linked with more than one y).

Answer 5
