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

domain

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

f (x) = \frac{x}{( 1 + ∣ x ∣ )}

arcsin (lo g_{10} (\frac{x}{10}))

f (x) = \frac{2 x - 1}{2 x}

\frac{5 + x}{5 - x}

x - 4 - 2
