domain of f(x)=-1/4 x^3-13x^2+3x-9

domain

f (x) = - \frac{1}{4} x^{3} - 13 x^{2} + 3 x - 9

- \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

6 x - 1248

f (x) = \frac{2 x + 9}{x ^{2} - 5 x - 6}

\frac{2}{x} - 1

x^{3} - 3 x^{2} + 3 x - 7

f (x) = x + \frac{34}{4}
