domain of (2x-5)/(x(x-3))

domain

\frac{2 x - 5}{x ( x - 3 )}

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 = 0, x = 3

The function domain

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

f (x) = - x^{3} + x^{2} + 12 x

f (x) = x^{2} + 3 x + 4

\frac{3}{2} 4 - x^{2}

\frac{1}{4 - x}

f (x) = \frac{x + 10}{x - 8}

What is the domain of (2x-5)/(x(x-3)) ?
The domain of (2x-5)/(x(x-3)) is x<0\lor 0<x<3\lor x>3
