domain of f(x)=-(8x)/(x^2-4)

domain

f (x) = - \frac{8 x}{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) = x^{4} + x^{3} - 4 x^{2} + 5

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

lo g_{5} (\frac{x}{x + 1})

\frac{1}{3 - x}

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

What is the domain of f(x)=-(8x)/(x^2-4) ?
The domain of f(x)=-(8x)/(x^2-4) is x<-2\lor-2<x<2\lor x>2
