bro the meme isn't right

for a limit to be correct, the left hand limit and the right hand limit must equal each other.
>RH Limit approaches L as the x approaches the x value from the righthand side
>LH Limit approaches L as the x approaches the x value from the lefthand side


for f(x)=-1/(x^2)

the right hand limit of f(x) as x approaches 0 is neg. inf.

>it would look like
>lim f(x)
>x -> 0^(+)
>see image

The left hand limit of f(x) as x approaches 0 is neg. inf.

>it would look like
>lim f(x)
>x -> 0^(-)
>see image

RH Limit of f(x) and LH limit of f(x) equal neg. inf.
so the limit of -1/(x^2) as x approaches 0 is neg. inf.
