domain of f(x)= 1/(-3x^2-3x+18)

domain

f (x) = \frac{1}{- 3 x ^{2} - 3 x + 18}

x < - 3 or - 3 < x < 2 or x > 2

Interval Notation

(- \infty, - 3) \cup (- 3, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3, x = 2

The function domain

x < - 3 or - 3 < x < 2 or x > 2
