domain of f(x)=(x^2-16)/(sqrt(18-2x^2))

domain

f (x) = \frac{x ^{2} - 16}{18 - 2 x ^{2}}

- 3 < x < 3

Interval Notation

(- 3, 3)

Solution steps

Find non-negative values for radicals:

- 3 \leq x \leq 3

Find undefined (singularity) points:

x = 3, x = - 3

Combine real regions and undefined points for final function domain

- 3 < x < 3

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

f (x) = ∣ x + 1 ∣ + ∣ x - 1 ∣

f (x) = x^{\frac{1}{3}} (x + 4)

\frac{x + 3}{x - 5}

f (x) = 9 x + 1
