domain of f(x)= 1/(x^2-9)

Solution

domain

f (x) = \frac{1}{x ^{2} - 9}

Solution

x < - 3 or - 3 < x < 3 or x > 3

+1

Solution steps

Find undefined (singularity) points:

x = 3, x = - 3

The function domain

x < - 3 or - 3 < x < 3 or x > 3

Popular Examples

f (g) = g

line (-4,-5),(-2,-6)line

(- 4, - 5), (- 2, - 6)

line (3,4),(-3,2)line

(3, 4), (- 3, 2)

line f(x)=-7-7/4 x line

f (x) = - 7 - \frac{7}{4} x

inverse of f(x)=6x^2-4 inverse

f (x) = 6 x^{2} - 4
