domain of f(x)=(x+8)/(x-4)

domain

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

ln (x)

f (x) = \frac{x - 5}{2 x ( 3 x - 5 )}

\frac{4}{x ^{2} - 3 x - 4}

f (x) = \frac{1}{2 x ^{2} + 5 x - 3}

y = 4 x - 1

What is the domain of f(x)=(x+8)/(x-4) ?
The domain of f(x)=(x+8)/(x-4) is x<4\lor x>4
