Question

The graph of the function f(x)=10/x+2 is shown below. What is the vertical asymptote of the function? x = –10 x = –2 x = 0 x = 2

Answer 1

Option B which is -2

Answer 2

Red line.
Answer: x = -2

$f(x)=\dfrac{10}{x+2}\\\\x+2\neq0\to x\neq-2$
Therefore, the vertical asymptote of function f(x) is x = -2.
