domain of f(x)=(x-4)/(x+4)

domain

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

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

y = tan (\frac{π}{4} x)

f (x) = 2 + 7 x

f (x) = 2^{1 - x}

f (x) = x^{2} - 16

f (x) = e^{- x} + 4

What is the domain of f(x)=(x-4)/(x+4) ?
The domain of f(x)=(x-4)/(x+4) is x<-4\lor x>-4
