domain of (3x-2)/(x^3-9x)

domain

\frac{3 x - 2}{x ^{3} - 9 x}

x < - 3 or - 3 < x < 0 or 0 < x < 3 or x > 3

Interval Notation

(- \infty, - 3) \cup (- 3, 0) \cup (0, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 3, x = 3

The function domain

x < - 3 or - 3 < x < 0 or 0 < x < 3 or x > 3

∣ x ∣ + ∣ x - 1 ∣

f (x) = x^{3} + 2 x

ln (4 x - x^{2})

f (x) = 3 x^{2} - 4 x - 5

y = \frac{x}{2} + 4
