domain of cos(arctan(1-x^2))

domain

cos (arctan (1 - 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

f (x) = \frac{x ^{2} - 9 x - 36}{x + 16}

1 + ln (x^{3} - 8)

f (x) = \frac{1}{1 - cos ^{2} ( x - \frac{3}{2} )}

\frac{x + 8}{3}

y = - (0.02)^{x + 6}
