domain of 8/(t^2-81)

Solution

domain

\frac{8}{t ^{2} - 81}

Solution

t < - 9 or - 9 < t < 9 or t > 9

+1

Interval Notation

(- \infty, - 9) \cup (- 9, 9) \cup (9, \infty)

Solution steps

Find undefined (singularity) points:

t = 9, t = - 9

The function domain

t < - 9 or - 9 < t < 9 or t > 9

Popular Examples

inflection x^3-9x^2+27x+3 inflection points

x^{3} - 9 x^{2} + 27 x + 3

inflection f(x)=8-3x^2-x^3 inflection points

f (x) = 8 - 3 x^{2} - x^{3}

inverse of f(x)=(\sqrt[5]{x}+2)^7 inverse

extreme f(x)=2x-2 extreme points

f (x) = 2 x - 2

domain of f(x)= 5/(x+10)domain

f (x) = \frac{5}{x + 10}
