evaluate the limit, if it exists. (if an answer does not exist, enter\n lim_{x\rightarrow6}\frac{\frac{1}{x}-\frac{1}{6}}{x - 6}
Answer
Explanation:
Step1: Combine the fractions in the numerator
First, find a common - denominator for $\frac{1}{x}-\frac{1}{6}$. The common denominator is $6x$. So, $\frac{1}{x}-\frac{1}{6}=\frac{6 - x}{6x}$. The original limit becomes $\lim_{x\rightarrow6}\frac{\frac{6 - x}{6x}}{x - 6}$.
Step2: Simplify the complex - fraction
$\frac{\frac{6 - x}{6x}}{x - 6}=\frac{6 - x}{6x(x - 6)}$. Notice that $6 - x=-(x - 6)$. So, $\frac{6 - x}{6x(x - 6)}=\frac{-(x - 6)}{6x(x - 6)}$.
Step3: Cancel out the common factor
Cancel out the common factor $(x - 6)$ (for $x\neq6$). We get $\lim_{x\rightarrow6}\frac{-1}{6x}$.
Step4: Evaluate the limit
Substitute $x = 6$ into $\frac{-1}{6x}$. We have $\frac{-1}{6\times6}=-\frac{1}{36}$.
Answer:
$-\frac{1}{36}$
