which is an asymptote of the graph of the function $y = \\cot(x - \\frac{2\\pi}{3})$?\n$x=-\frac{2\\pi}{3}$\n$x = -\frac{\\pi}{3}$\n$x=\frac{4\\pi}{3}$\n$x=\frac{7\\pi}{3}$
Answer
Answer:
B. $x =-\frac{\pi}{3}$
Explanation:
Step1: Recall cotangent asymptote formula
The cotangent function $y = \cot(u)$ has asymptotes at $u = n\pi$, where $n\in\mathbb{Z}$. For the function $y=\cot(x - \frac{2\pi}{3})$, set $x-\frac{2\pi}{3}=n\pi$.
Step2: Solve for $x$
$x=n\pi+\frac{2\pi}{3}$.
Step3: Find the correct option
When $n = - 1$, $x=-\pi+\frac{2\pi}{3}=-\frac{\pi}{3}$.
