domain of f(x)=(x+4)/(x^2-36)

domain

f (x) = \frac{x + 4}{x ^{2} - 36}

x < - 6 or - 6 < x < 6 or x > 6

Interval Notation

(- \infty, - 6) \cup (- 6, 6) \cup (6, \infty)

Solution steps

Find undefined (singularity) points:

x = 6, x = - 6

The function domain

x < - 6 or - 6 < x < 6 or x > 6

f (x) = x^{2} - x - 1

y = lo g_{5} (x)

0.001 x^{3} + 4 x + 686

y = cos^{2} (x)

f (x) = 2 - 5 x

What is the domain of f(x)=(x+4)/(x^2-36) ?
The domain of f(x)=(x+4)/(x^2-36) is x<-6\lor-6<x<6\lor x>6
