domain of f(x)=x^3-3x^2-9x-27

domain

f (x) = x^{3} - 3 x^{2} - 9 x - 27

- \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) = - 4 x^{2} + 6 x + 1

f (R) = R^{4}

f (a) = \frac{5}{a ^{3}}

P (x) = x^{3} - 2 x^{2} - 5 x + 6

f (x) = ln (2 x + 5)
