Use graphs and tables to find the limit and identify any vertical asymptotes of
@KeithAfasCalcLover
In general for a function of the form: \[f(x)=\frac{1}{x-d}+c\] Which is just a translated version of \(f(x)=\frac{1}{x}\), the limits exist like so: \[\lim_{x\to d^-}f(x)=-\infty\textit{ and...}\lim_{x\to d^+}f(x)=\infty\] So in our case, we have the \(d\) value as 3 so therefore: \[\lim_{x\to3^-}=-\infty\]
So, -∞ ; x = -3?
Pardon me?
As x approaches 3 from the negative side, f(x) approaches - infinity
Is -∞ ; x = -3 the correct answer
Ehh oh I get it... no it would be: \[-\infty;x=3\]
Oh, okay. Why 3, and not -3?
In accordance with the same function, if we had the function \[f(x)=\frac{1}{x-d}+c\] We know that \(x\neq d\) because then we end up with an undefined value right? So then we know that with the function: \[f(x)=\frac{1}{x-3};x\neq3\]
Okay.
