jtvatsim · Answer

$$\lim_{x\rightarrow ^+1} \frac{ (2x^2−x−3)}{(2x^2−5x+3)}$$

lolz

jtvatsim · Answer

OK, so the +1 just means that the limit is approaching 1 from the right side of the graph. It is a "one-sided limit" if you've heard of that term.

anikate · Answer

is there such thing as a two sided?

anikate · Answer

@jtvatsim

jtvatsim · Answer

Yes, most limits are two-sided. This is what is indicated by having no + or - sign under the limit.

anikate · Answer

oh ok, so what is the significance of the +?

jtvatsim · Answer

The + restricts the limit to coming only from the right side of the graph, a picture will help.
