domain of f(x)=(2x-8)/(x+2)

domain

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

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

y = e^{- x}

f (x) = \frac{x}{2 x - 9}

\frac{( x + 8 )}{( x ^{2} - 2 x - 15 )}

f (x) = \frac{1}{4 - 2 - x}

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

What is the domain of f(x)=(2x-8)/(x+2) ?
The domain of f(x)=(2x-8)/(x+2) is x<-2\lor x>-2
