domain of f(x)=(x+3)/(x-8)

domain

f (x) = \frac{x + 3}{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 - 9

f (x) = 7 x + 11

2 = - \frac{1}{2} + c

y = x^{2} + 5 x

f (x) = x - 3

What is the domain of f(x)=(x+3)/(x-8) ?
The domain of f(x)=(x+3)/(x-8) is x<8\lor x>8
