domain of g(x)=(sqrt(x+5))/(sqrt(x^2-9))

domain

g (x) = \frac{x + 5}{x ^{2} - 9}

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

Interval Notation

[- 5, - 3) \cup (3, \infty)

Solution steps

Find non-negative values for radicals:

- 5 \leq x \leq - 3 or x \geq 3

Find undefined (singularity) points:

x = 3, x = - 3

Combine real regions and undefined points for final function domain

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

ln (2 - y^{2})

y = \frac{4 x + 60}{ln ( 5 x - 40 )}

∣ x ∣ - x

- 11

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

What is the domain of g(x)=(sqrt(x+5))/(sqrt(x^2-9)) ?
The domain of g(x)=(sqrt(x+5))/(sqrt(x^2-9)) is -5<= x<-3\lor x>3
