domain of 1/(x-9)

Solution

domain

\frac{1}{x - 9}

Solution

x < 9 or x > 9

+1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 9

The function domain

x < 9 or x > 9

Popular Examples

domain of f(x)=(x-5)/(x^2+10x+25)domain

f (x) = \frac{x - 5}{x ^{2} + 10 x + 25}

domain of y=sqrt(x-4)domain

y = x - 4

range of f(x)= 1/((x-8)^2)range

f (x) = \frac{1}{( x - 8 ) ^{2}}

inverse of f(x)=x^3+10 inverse

f (x) = x^{3} + 10

inverse of f(x)=3log_{2}(x)inverse

f (x) = 3 lo g_{2} (x)
