domain of f(x)=(-8)/(x+7)

domain

f (x) = \frac{- 8}{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) = - 6 x^{5} + 7 x^{3}

\frac{3 + x ^{4}}{x ^{2} - x ^{4}}

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

\frac{1}{x ^{2} + 4}

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

What is the domain of f(x)=(-8)/(x+7) ?
The domain of f(x)=(-8)/(x+7) is x<-7\lor x>-7
