domain of (8x)/(9x-4)

domain

\frac{8 x}{9 x - 4}

x < \frac{4}{9} or x > \frac{4}{9}

Interval Notation

(- \infty, \frac{4}{9}) \cup (\frac{4}{9}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{4}{9}

The function domain

x < \frac{4}{9} or x > \frac{4}{9}

f (x) = \frac{8 x}{x - 5}

\frac{3 t - 9}{3 t ^{2} - 12}

arccos (2 x)

f (x) = 3 x^{4} - 7

f (x) = 6 x^{2} - 6

What is the domain of (8x)/(9x-4) ?
The domain of (8x)/(9x-4) is x< 4/9 \lor x> 4/9
