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

domain

f (x) = cos (arctan (1 - x^{2}))

- \infty < x < \infty

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

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

f (x) = 3 x^{2} - 5 x - 2

f (x) = 2 ∣ x ∣

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

f (x) = (100 - x^{2})^{\frac{5}{2}}
