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

domain

\frac{x + 2}{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

- 2 x^{3} - 6 x^{2} + 18 x + 1

f (x) = 11

f (y) = 2 x + b

f (x) = x^{2} - 6 x + 9

x^{3} - 4 x^{2} - 16 x + 9

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