domain of f(x)= 5/(x^2-4)

domain

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

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

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

f (x) = 8 x + 6

m = 0, (0, 1)

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

\frac{2 x}{x ^{2} - 1}

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

What is the domain of f(x)= 5/(x^2-4) ?
The domain of f(x)= 5/(x^2-4) is x<-2\lor-2<x<2\lor x>2
