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

domain

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

x < - 2 or 0 \leq x < 2

Interval Notation

(- \infty, - 2) \cup [0, 2)

Solution steps

Find non-negative values for radicals:

x < - 2 or 0 \leq x < 2

Find undefined (singularity) points:

x = 2, x = - 2

Combine real regions and undefined points for final function domain

x < - 2 or 0 \leq x < 2
