domain of f(x)=(x^4)/9-2x^2

domain

f (x) = \frac{x ^{4}}{9} - 2 x^{2}

- \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{x - 1}{1 - x}

f (x) = arccos (\frac{x + 3}{8})

f (x) = \frac{x + 4}{x ^{2} + 5 x - 14}

ln (- \frac{- 5 - 3 x ^{2}}{x ^{2} + 1})

- ln (1 - ln (x))
