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

domain

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

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 3, x = - 3

The function domain

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

m = - \frac{1}{2}, (4, 1)

\frac{( x ^{3} - 9 x )}{x + 2}

(15 - 12) (- 26 6)

sec (x)

f (x) = \frac{1}{2} x - 10 + 3

What is the domain of (x+2)/(x^2-9) ?
The domain of (x+2)/(x^2-9) is x<-3\lor-3<x<3\lor x>3
