Question

At what value of x does the graph of the following function F(x) have a

vertical asymptote?
A. 2
B. 2
C. -1
D. 0

Answer 1

Given:

The function is

`F(x)=(1)/(x+2)`

To find:

The vertical asymptote of the given function.

Solution:

Vertical asymptote are the vertical line passes thought the values for which the function is not defined.

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

We have,

`F(x)=(1)/(x+2)`

Denominator is (x+2).

`x+2=0`

`x=-2`

The vertical asymptote is
`x=-2`.

Therefore, the correct option is B.
