domain of 1/(1+e^{-2x)}

domain

\frac{1}{1 + e ^{- 2 x}}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

\frac{5}{x - 4}

f (x) = \frac{x - 1}{x}

f (x) = \frac{x ^{2} + 1}{2 x + 2}

y = \frac{4}{\frac{2}{x - 1} + 3}

\frac{3 x + 1}{5}
