domain of y= 1/(3x-x^2)

domain

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

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

What is the domain of y= 1/(3x-x^2) ?
The domain of y= 1/(3x-x^2) is x<0\lor 0<x<3\lor x>3
