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

ln (x^{2} - 2 x)

f (x) = \frac{x - 3}{7 x}

f (x) = \frac{2 x ^{2} - 9}{x ^{2} - 9}

y = 2 csc (x)

\frac{1}{( x ^{2} - 9 )}
