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

domain

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

- \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{( 9 x - 4 )}{4 x - 5}

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

lo g_{9} (x^{2} - 16)

\frac{2 x + 1}{x ^{2} - 9}

\frac{3 x - 8}{25}

What is the domain of f(x)=(x^3-x-1)/(x^2+x+1) ?
The domain of f(x)=(x^3-x-1)/(x^2+x+1) is -infinity <x<infinity
