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

domain

f (x) = \frac{4}{x - 8}

x < 8 or x > 8

Interval Notation

(- \infty, 8) \cup (8, \infty)

Solution steps

Find undefined (singularity) points:

x = 8

The function domain

x < 8 or x > 8

f (x) = x - 2 + 2

f (x) = 2 x + 4

f (x) = \frac{( e ^{x} )}{x ^{2}}

f (x) = 5 x - 4 x^{2}

f (x) = 4 x - 1

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