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

domain

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

x \leq - 4 or x > 2

Interval Notation

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

Solution steps

Find non-negative values for radicals:

x \leq - 4 or x > 2

Find undefined (singularity) points:

x = 2

Combine real regions and undefined points for final function domain

x \leq - 4 or x > 2

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