domain of f(x)= 3/x+9

Solution

domain

f (x) = \frac{3}{x} + 9

Solution

x < 0 or x > 0

+1

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

extreme f(x)=-x^5-3x^4+2x^2 extreme points

f (x) = - x^{5} - 3 x^{4} + 2 x^{2}

asymptotes of f(x)=(cos(x))/x asymptotes

f (x) = \frac{cos ( x )}{x}

asymptotes of f(x)=(5+4x)/(x+3)asymptotes

f (x) = \frac{5 + 4 x}{x + 3}

range of f(x)= 1/(sqrt(1-x^2))range

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

critical x+5 critical points

x + 5
