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

domain

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

- 2 \leq x \leq 2 or x > 4

Interval Notation

[- 2, 2] \cup (4, \infty)

Solution steps

Find non-negative values for radicals:

- 2 \leq x \leq 2 or x > 4

Find undefined (singularity) points:

x = 4

Combine real regions and undefined points for final function domain

- 2 \leq x \leq 2 or x > 4

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