This is not a hard question. Tell us what you have tried so far.
not to worry sorry i figured out that because it has the same -1 on both plots it is not a function.
what about this one-
The points (1, 3) and (2, 3) satisfy a relation R, which of the following can we (definitely) conclude?
a. R is a function
b. R is not a function
c. R is y=3
d. R is a straight line
e. None of the above
I know its a straight line and is function but neither answers are right? what would be the right answer?
