domain of f(x)=(2x)/(9x-1)

domain

f (x) = \frac{2 x}{9 x - 1}

x < \frac{1}{9} or x > \frac{1}{9}

Interval Notation

(- \infty, \frac{1}{9}) \cup (\frac{1}{9}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{1}{9}

The function domain

x < \frac{1}{9} or x > \frac{1}{9}

y = 2 x - 4

f (x) = x^{2} - 10 x + 21

f (x) = \frac{7 x}{8 x - 3}

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

\frac{2 x ^{2} - 4}{3 x ^{2} + 6 x - 45}

What is the domain of f(x)=(2x)/(9x-1) ?
The domain of f(x)=(2x)/(9x-1) is x< 1/9 \lor x> 1/9
