Actually, there are cases where you get more than one answer. Such as f(x)=x^2. If f(x)=4, then the x has two possible solutions: -2 and 2. But that's just the most prominent example.

@Grenartia: I meant the math on approaching zero, but I won't deny that you are right on positive and negative integers.

@GreenKrog:

I didn't notice any limits, and didn't see anything that would cause the function to be anything other than 0 as x approaches 0. Also, it is sometimes possible for one side of a limit to go to positive infinity, and the other side to go to negative infinity, so even then, more than one answer. :P

@Grenartia: No no, what she is talking about, not the actual written numbers in the first frame.

@GreenKrog: I might be reading it wrong, but if it is equivalently f(x+c)=x^2 + 2xc +c^2, then by factoring it would be the same as f(x+c)=(x+c)^2 or f(x)=x^2 (though Annie got 2x, so they don't quite line up). The notation is just confusing me terribly, but then again, math notation without a strong formatting engine is difficult.

@Bandana_girl: Not gonna lie. I probably pulled this from a website because either I am way too drunk to deal with the math or my math ability died when I became a girl/left high school. I am not sure why there is a ? in the equation at all, I suspect something was lost in a copy-paste. I get the feeling they should be notated and not simple multipliers though.

Stop overthinking the math, it is probably the only thing in the comic I cant explain :)
