domain of f(x)=(x-2)/(x^2-9)

domain

f (x) = \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

ln (2 x + 5)

f (x) = \frac{x - 1}{4 + x ∣ x ∣}

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

f (x) = lo g_{10} (6 - x)

6 x - 4

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