Answer: First option.
Step-by-step explanation:
You need to remember the following Trigonometric Identity:
In this case, you can identify in the figure that:
Then you must substitute these values into :
Finally, you need to solve for "x" in order to find its value. This is:
Rounding the result to the nearest tenth, you get:
Given:
The function is
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,
Denominator is (x+2).
The vertical asymptote is .
Therefore, the correct option is B.
