domain of 2e^{-x}arctan(x)

domain

2 e^{- x} arctan (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) = - 2 x^{3}

e^{x^{3} - 6 x^{2} - 16 x} (3 x^{2} - 12 x - 16)

f (x) = \frac{4 x + 3}{x ^{3} - 2 x}

\frac{2 x + 3}{( 5 x - 1 ) ( x - 2 ) ^{0.5}}

f (x) = \frac{1}{x ^{2} + x - 12}
