domain of f(x)= 9/(x-8)

domain

f (x) = \frac{9}{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

(a, 4), (5, b)

f (x) = \frac{15}{x}

f (x) = ∣ 8 - x ∣

y = \frac{1}{x - 2} + 1

4 x - y = - 8

What is the domain of f(x)= 9/(x-8) ?
The domain of f(x)= 9/(x-8) is x<8\lor x>8
