domain of f(x)=(2^x-2^{-x})/(2^x+2^{-x)}

domain

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

f (x) = \frac{x - 7}{2}

f (x) = \frac{- x - 10}{x ^{3}}

f (x) = \frac{x - 2}{x ^{2} - 81}

h (x) = - x + 2
