domain of sqrt((x^2+3x)/(x^2-16))

domain

\frac{x ^{2} + 3 x}{x ^{2} - 16}

x < - 4 or - 3 \leq x \leq 0 or x > 4

Interval Notation

(- \infty, - 4) \cup [- 3, 0] \cup (4, \infty)

Solution steps

Find non-negative values for radicals:

x < - 4 or - 3 \leq x \leq 0 or x > 4

Find undefined (singularity) points:

x = 4, x = - 4

Combine real regions and undefined points for final function domain

x < - 4 or - 3 \leq x \leq 0 or x > 4

y = 2 - 9 - (x + 2)^{2}

f (x) = \frac{x ^{2} - 10}{x ^{2} - 4}

ln (3 x - 5)

f (x) = \frac{5}{x ^{2} + x - 12}

\frac{x - 1}{x + 5}
