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

domain

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

\frac{1}{t + 2} + t + 1

y = e

y = 5 - 2 x^{2}

y = 9

\frac{1 - 8 x}{5}
