domain of f(x)=(15)/(3/x-1)

domain

f (x) = \frac{15}{\frac{3}{x} - 1}

x < 0 or 0 < x < 3 or x > 3

Interval Notation

(- \infty, 0) \cup (0, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3, x = 0

The function domain

x < 0 or 0 < x < 3 or x > 3

\frac{2 x}{3 x + 6}

f (x) = - 5 x + 4 - x - 2

lo g_{5} (5 - 2 x)

- x^{2} + 3 x

y = \frac{3 x ^{2} + 7 x - 1}{x + 1}

What is the domain of f(x)=(15)/(3/x-1) ?
The domain of f(x)=(15)/(3/x-1) is x<0\lor 0<x<3\lor x>3
