domain of f(x)= x/(9x-2)

domain

f (x) = \frac{x}{9 x - 2}

x < \frac{2}{9} or x > \frac{2}{9}

Interval Notation

(- \infty, \frac{2}{9}) \cup (\frac{2}{9}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{2}{9}

The function domain

x < \frac{2}{9} or x > \frac{2}{9}

f (x) = \frac{( 3 x + 2 )}{1 - x}

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

y = \frac{1}{- 4 x ^{2} - 20 x - 21}

f (x) = \frac{x + 6}{x - 8}

g (x) = 3 x^{2} - 81

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