domain of (-2x+9)/(x-3)

domain

\frac{- 2 x + 9}{x - 3}

x < 3 or x > 3

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

ln (50 - x^{2})

x - x^{2} - x - 2

\frac{1}{6 x - 12}

f (x) = lo g_{2} (\frac{2 x}{3} - 4)

f (x) = \frac{x ^{3} - x ^{2} - 13 x - 3}{x + 3}

What is the domain of (-2x+9)/(x-3) ?
The domain of (-2x+9)/(x-3) is x<3\lor x>3
