I know at least 1 will be wrong. Please explain why.

anonymous · Answer

yeah they are all false

anonymous · Answer

oh no actually the third one  is right, sorry

anonymous · Answer

as $x\to 1^-$ you have $f(x)\to -\infty$ so the limit does not exist

anonymous · Answer

Because of the "open" hole on  0,0, do you just jump to the closed hole at 1,1? [infinity]?

anonymous · Answer

the limit as x goes to 1 from below has nothing to do with the limit at 0

anonymous · Answer

as x approaches 1 from the left, the function is going down to $-\infty$
that is why the limit does not exist

anonymous · Answer

To approach this problem. "1 from the left" Do I start in quadrant 1, and follow the line down?

anonymous · Answer

I thought that was only true from the right.
