domain of f(x)=(9x)/(x^2-16)

domain

f (x) = \frac{9 x}{x ^{2} - 16}

x < - 4 or - 4 < x < 4 or x > 4

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 4, x = - 4

The function domain

x < - 4 or - 4 < x < 4 or x > 4

\frac{3 2 ^{2}}{2 ^{2} + 1}

f (x) = 3 x^{5} + x^{3}

(- 4, - 10), (9, 9)

2 cos (11 x) + 6

f (x) = - 2 x - 4

What is the domain of f(x)=(9x)/(x^2-16) ?
The domain of f(x)=(9x)/(x^2-16) is x<-4\lor-4<x<4\lor x>4
