Best ResponseYou've already chosen the best response.0(x+7)/(x^24) limit approaches 2 negatively between 2 and 2 the denominator is negative but once it passes 2 it becomes +infinity so shouldn't it be +infinity instead of infinity?

Best ResponseYou've already chosen the best response.1If you haven't already, graph the equation on your graphing calculator. As you'll notice, if the limit is appoaching 2 from the left, then the answer will be positive infinity. However, if the limit is approaching 2 from right, then the answer will be infinity.

Best ResponseYou've already chosen the best response.0so then instead of looking at the direction of y, I would look at the direction of x?

Best ResponseYou've already chosen the best response.1Does the limit in the problem look something like this? \[\lim_{n \rightarrow 2^+}\]

Best ResponseYou've already chosen the best response.0\[g(x)=x+7/x ^{2}4\] \[\lim_{x \rightarrow 2^} g(x)\]

Best ResponseYou've already chosen the best response.1All right, see how there is a "" sign above the 2? The negative sign means that the limit is approaching 2 from the left side. If there was a "+" sign above the 2, then the limit would be apporaching 2 from the right side. So, yes, it's how you look at from the direction of x.
