domain of (9x^2-1)/(9x^3+6x^2+x)

domain

\frac{9 x ^{2} - 1}{9 x ^{3} + 6 x ^{2} + x}

x < - \frac{1}{3} or - \frac{1}{3} < x < 0 or x > 0

Interval Notation

(- \infty, - \frac{1}{3}) \cup (- \frac{1}{3}, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - \frac{1}{3}

The function domain

x < - \frac{1}{3} or - \frac{1}{3} < x < 0 or x > 0

y = \frac{π}{4} + sin (x)

5 x + 20

f (x) = 22 x

f (x) = \frac{x}{x + 2}

f (x) = x^{8} e^{x} - 6
