domain of f(x)=(2x-4)/(x+4)

domain

f (x) = \frac{2 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 = x - 3

f (x) = \frac{6}{x ^{2} - 9}

- 2 + e^{3 x} (4 - 2 x)

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

y = (2 x)^{\frac{1}{3}} - 7

What is the domain of f(x)=(2x-4)/(x+4) ?
The domain of f(x)=(2x-4)/(x+4) is x<-4\lor x>-4
