domain of f(x)= 1/(sqrt(x^2-4))

domain

f (x) = \frac{1}{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

f (x) = 5 csc (2 x) - 5

(0.9) (5.4)

y = 0.5 x^{2} - 3

f (t) = (cos (t), ln (t), \frac{1}{t - 2})

5 - x + 25

What is the domain of f(x)= 1/(sqrt(x^2-4)) ?
The domain of f(x)= 1/(sqrt(x^2-4)) is x<-2\lor x>2
