domain of (x^3+8)/(x^2-8)

domain

\frac{x ^{3} + 8}{x ^{2} - 8}

x < - 22 or - 22 < x < 22 or x > 22

Interval Notation

(- \infty, - 22) \cup (- 22, 22) \cup (22, \infty)

Solution steps

Find undefined (singularity) points:

x = 22, x = - 22

The function domain

x < - 22 or - 22 < x < 22 or x > 22

3 x + 2 y = 2

f (x) = - 5 x + 8 y = 14

f (x) = x^{2} e^{x} - 7

f (x) = \frac{2 x - 7}{x ^{2} - 5 x + 6}

16 x + 13 y = 26

What is the domain of (x^3+8)/(x^2-8) ?
The domain of (x^3+8)/(x^2-8) is x<-2sqrt(2)\lor-2sqrt(2)<x<2sqrt(2)\lor x>2sqrt(2)
