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

domain

f (x) = \frac{4 x ^{2}}{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

- 2 + lo g_{4} (x + 3)

f (x) = x^{3} - 27

e^{y}

\frac{x + 8}{( x - 6 ) ( x + 8 )}

lo g_{10} (x - x^{2})

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