domain of f(x)=1+x-x^2-x^3

domain

f (x) = 1 + x - x^{2} - x^{3}

- \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

\frac{3}{4} cos (x)

4 - x + 2

f (x) = \frac{x ^{2} + x - 12}{x - 3}

(- 1, 4), (2, 2)

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