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

domain

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

x < - 2 or x > 2

Interval Notation

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

Solution steps

Find non-negative values for radicals:

x \leq - 2 or x \geq 2

Find undefined (singularity) points:

x = 2, x = - 2

Combine real regions and undefined points for final function domain

x < - 2 or x > 2

(- \frac{2}{6}) m = \frac{2}{3}

y = e^{x - 4}

(x + 2)^{\frac{6}{7}}

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

f (x) = \frac{x ^{3} - 32}{x - 3}

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