Does the graph of the function f(x) = x^2 − 8x − 9 / x + 1 have a vertical asymptote or a point missing at x = −1? explain
your reasoning, and support your answer numerically.

Yes, the graph of the function has vertical asymptote at x=-1.

Step-by-step explanation:

Given : Function

To find : Does the graph of the function have a vertical asymptote or a point missing at x = −1?

Solution :

The vertical asymptote of the rational function is when we put denominator equals to zero.

In the function

Denominator -

Vertical asymptote is at

Yes, the graph of the function has vertical asymptote at x=-1.

(x) - (y) = (1 + 4i)
