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

domain

\frac{x ^{2} + 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

f (x) = e^{s i n (x)}

\frac{x + 4}{x ^{2} - 5 x + 6}

- 6 (x + 1) - 3

y = - 3 lo g_{4} (5 - x)

f (x) = x - 2 - lo g_{5} (10 - x)

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