domain of f(x)=(8-x)/(x+3)

domain

f (x) = \frac{8 - x}{x + 3}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

\frac{1}{x ^{2}} - 1

f (x) = \frac{- 3 x}{x - 1}

f (x) = \frac{- x ^{2} + 4}{- x}

f (x) = 81 x

y = \frac{x ^{3}}{8} - \frac{x}{6} + c x^{- 5}

What is the domain of f(x)=(8-x)/(x+3) ?
The domain of f(x)=(8-x)/(x+3) is x<-3\lor x>-3
