The discussion revolves around evaluating the limits of two functions as x approaches specific values: the first function as x approaches 0 and the second as x approaches -1. The subject area pertains to calculus, specifically the concept of limits.
Participants have provided feedback on the original poster's attempts, with some affirming the calculations while seeking further elaboration on the second limit. The discussion appears to be productive, with multiple perspectives being explored regarding the limit's behavior as x approaches -1.
There is a noted uncertainty from the original poster about the limit at x = -1, and participants are discussing the implications of approaching from different sides of that point.
Zondrina said:They both look good. Could you elaborate on part (b) a little more though?
NATURE.M said:Thanks.
For b:
lim 1/(x+1) = ∞ (+)
x→-1 (+)
lim 1/(x+1)= ∞ (-)
x→-1 (-)
Therefore, lim 1/(x+1)=undefined
x→-1
