domain of f(x)=(x+2)/(x+7)

domain

f (x) = \frac{x + 2}{x + 7}

x < - 7 or x > - 7

Interval Notation

(- \infty, - 7) \cup (- 7, \infty)

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

f (x) = - x^{3} - 9 x^{2} - 24 x - 1

f (x) = \frac{( x ^{2} + 20 )}{5 ( x - 2 ) ^{2}}

\frac{x ^{2} + x - 6}{x ^{3} - 1}

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

f (x) = 3 + (2 + x)^{\frac{1}{2}}

What is the domain of f(x)=(x+2)/(x+7) ?
The domain of f(x)=(x+2)/(x+7) is x<-7\lor x>-7
