domain of (3x-5)/(x^2+x+1)

domain

\frac{3 x - 5}{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{1}{x ^{3} - 5 x}

2 x^{2} + 7 x + 15

\frac{x + 1}{∣ x ∣ + 1}

9 x + 20

\frac{6}{x ^{2} + 4}
