domain of f(x)=e^{arctan(x)}

domain

f (x) = e^{a r c t a n (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

y, y \leq - x

f (x) = \frac{- 7 - 4 x}{7 ( - 1 - x )}

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

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

(5 x - 2) + (4 x + 1)
