domain of sqrt((3-x)/(x^2-4))

domain

\frac{3 - x}{x ^{2} - 4}

x < - 2 or 2 < x \leq 3

Interval Notation

(- \infty, - 2) \cup (2, 3]

Solution steps

Find non-negative values for radicals:

x < - 2 or 2 < x \leq 3

Find undefined (singularity) points:

x = 2, x = - 2

Combine real regions and undefined points for final function domain

x < - 2 or 2 < x \leq 3
