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

domain

f (x) = \frac{3 x}{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) = - 4 x + 1 = - 5

y = 1 - \frac{x ^{2}}{9}

\frac{1}{3} (x - 2.1)^{2} + 7.9

ln (- \frac{- 6 - 3 x ^{2}}{x ^{2} + 1})

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

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