domain of (x-3)/(x^2-4)

domain

\frac{x - 3}{x ^{2} - 4}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

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

f (x) = \frac{2 x}{5 - x}

f (x) = \frac{4 x}{5} - 1

f (x) = x^{2} - x^{4}

f (x) = ∣ x ∣ - x

\frac{\frac{x}{x + 5}}{\frac{x}{x + 5} + 5}

What is the domain of (x-3)/(x^2-4) ?
The domain of (x-3)/(x^2-4) is x<-2\lor-2<x<2\lor x>2
