domain of sqrt((x-2)/(x^3-2x^2-15x))

domain

\frac{x - 2}{x ^{3} - 2 x ^{2} - 15 x}

x < - 3 or 0 < x \leq 2 or x > 5

Interval Notation

(- \infty, - 3) \cup (0, 2] \cup (5, \infty)

Solution steps

Find non-negative values for radicals:

x < - 3 or 0 < x \leq 2 or x > 5

Find undefined (singularity) points:

x = 0, x = - 3, x = 5

Combine real regions and undefined points for final function domain

x < - 3 or 0 < x \leq 2 or x > 5

f (x) = \frac{( x - 10 ) ^{\frac{1}{3}}}{7}

f (x) = \frac{x - 1}{x ^{2} - 9}

\frac{3 x ^{2} - 27}{x ^{2} + 6 x + 9}

f (x) = x^{2} - 1, x \geq 0

f (x) = \frac{x + 5}{2}
