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

domain

f (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{2 ^{4 x - 1} \cdot 3 ^{x - 2}}{1 2 ^{x - 2}}

lo g_{2} (x^{2} - 1)

ln (2 t - 1)

\frac{3 x - 1}{2 x + 3}

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