Which of the following is true about $$f\left(x\right)=3\cos\left(\pi x\right)-1$$ ?

$$f^{-1}\left(x\right)=\frac{1}{\pi}\cos^{-1}\left(\frac{x+1}{3}\right)$$ and the domain of $$f^{-1}\left(x\right)$$ is [-4, 2]

$$f^{-1}\left(x\right)=\pi\cos^{-1}\left(\frac{x+1}{3}\right)$$ and the domain of $$f^{-1}\left(x\right)$$ is [-1, 1]

$$f^{-1}\left(x\right)=\frac{1}{\pi}\cos^{-1}\left(\frac{x+1}{3}\right)$$ and the domain of $$f^{-1}\left(x\right)$$ is [-1, 1]

$$f^{-1}\left(x\right)=\pi\cos^{-1}\left(\frac{x+1}{3}\right)$$ and the domain of $$f^{-1}\left(x\right)$$ is [-4, 2]

Write an equation in general form to find all vertical asymptotes for the graph of $$y=\tan\left(2x\right)$$

$$x\ =\ \frac{\pi}{4}+\frac{\pi}{2}k$$ , where k is an integer.

$$x\ =\ \frac{\pi}{2}+\pi k$$ , where k is an integer.

$$x\ =\ \frac{\pi}{4}+\pi k$$ , where k is an integer.

$$x\ =\ \frac{\pi}{2}+\frac{\pi}{2}k$$ , where k is an integer.
