domain of (x^2-4)/(x^2-x-6)

domain

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

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 3, x = - 2

The function domain

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

\frac{x + 6}{x - 7}

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

(x + 9)^{2} - 4

y = x^{2} + x - 3

x^{3} + 10
