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

24 x^{2} - 30 x + 4

y = - 0.000008 x^{2} - 0.0001 x + 0.0029

16 - x^{2} + x + 1

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

\frac{7 x + 2}{x ^{2} + x - 2}

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
