The domain includes all real numbers except those real numbers with the following form: $x = \frac{\pi}{4}+\frac{\pi~n}{2}$, where $n$ is an integer. The range includes all real numbers.
$f(x) = -4~tan(2x+\pi)$ The domain includes all real numbers, except values of $x$ such that $2x+\pi = \frac{\pi}{2}+\pi~n$, where $n$ is an integer. We can find an expression for these values of $x$: $2x+\pi = \frac{\pi}{2}+\pi~n$, where $n$ is an integer. $2x = \frac{\pi}{2}+\pi~n$, where $n$ is an integer. $x = \frac{\pi}{4}+\frac{\pi~n}{2}$, where $n$ is an integer. The domain includes all real numbers except those real numbers with the following form: $x = \frac{\pi}{4}+\frac{\pi~n}{2}$, where $n$ is an integer. The range includes all real numbers.
