domain of f(x)=\sqrt[3]{(x+2)/(1+x^2)}

domain

- \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{4 x + x ^{2}}{x ^{2} - x - 2}

f (x) = - \frac{x}{∣ x ∣}

f (x) = \frac{1}{x ^{4} + 2}

y = \frac{x ^{2}}{x + 3}

y = (25 - 4 x^{2}) + 4
