domain of sqrt((x^2-16)/(x^2+169))

domain

\frac{x ^{2} - 16}{x ^{2} + 169}

x \leq - 4 or x \geq 4

Interval Notation

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

Solution steps

Find non-negative values for radicals:

x \leq - 4 or x \geq 4

The function domain

x \leq - 4 or x \geq 4

f (x) = x^{3} - 3 x^{2} - 45 x

R^{240}

g (x) = \frac{x - 5}{x - 10}

y = 1075 x + 9396

f (x) = 3 - 5 cos (5 x)
