domain of f(x)=x(x-3)^{-1/4}

domain

f (x) = x (x - 3)^{- \frac{1}{4}}

x > 3

Interval Notation

(3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 3

Find undefined (singularity) points:

x = 3

Combine real regions and undefined points for final function domain

x > 3

What is the domain of f(x)=x(x-3)^{-1/4} ?
The domain of f(x)=x(x-3)^{-1/4} is x>3
