\(\lim_{x \rightarrow 2^-}f(x)= \) the y-value of f(x) left of 2 \(\lim_{x \rightarrow 2^+}f(x)= \) the y-value of f(x) right of 2

do you mind typing out the function so i can make sure i wrote it out right?
anonymous
  • anonymous
I don't really have a function typed out, and you don't really need it. The left limit is asking you as you go along the lines toward 2 from the left, what is the y-value you end up at? The right limit is asking the same thing about approaching 2 from the right|dw:1440033130819:dw|

in other words, what's the y-coordinates of the open circles?
anonymous
  • anonymous
4 and -2
anonymous
  • anonymous
right. Since the left limit is 4 and the right limit is -2, the "overall" limit approaching 2 doesn't exist
anonymous
  • anonymous
For the limit approaching 2 to exist, the left and right limits must be equal

oh ok cool. Do you mind helping me with one more?

ok so this one's asking for a left limit only. so use the line on the left.
anonymous
  • anonymous
so its the y coordinates of the open circle of the left line?
anonymous
  • anonymous
yes

oh ok. you know what it was. the answer was 1.3. i thinking it was just 1. But thanks for the help.
