Lim x→8- [1/(x-8)]=1/(8-8)=1/(-0)→Lim x→8- [1/(x-8)]=-Infinite

Vertical asymptote: x=8

Answer:

The limit of the function is [tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex] and the vertical asymptotes is x=8.

Step-by-step explanation:

The given function is

[tex]f(x)=\frac{1}{x-8}[/tex]

We need to find the value of

[tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}[/tex]

The graph of the function f(x) is attached below.

From the graph it is clear that the function approaches to -∞ as x approaches to 8 from left. So, by the graph we can say that

[tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex]

The table of values is attached below. From the table it is clear that the value of f(x) decreasing as the value of x is closed to 8 from left. So, by the table we can say that

[tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex]

To find the vertical asymptotes equate denominator, equal to 0.

[tex]x-8=0[/tex]

[tex]x=8[/tex]

Therefore the limit of the function is [tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex] and the vertical asymptotes is x=8.
