domain of 2^{-x}-1

domain

2^{- x} - 1

- \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 + 4)

f (x) = \frac{1}{x ^{4}}

y = \frac{5 x}{x + 6}

arccos (ln (x))

y = \frac{x ^{2} + 1}{x}
