Well, for function to be one to one, it must pass both horizontal and vertical line test, right?

geerky42 (geerky42):

For it to be just function, each input must have only one output. So for it to be one to one function, each output also must come from one input.

geerky42 (geerky42):

So what I said is that it's B.

geerky42 (geerky42):
