domain of (9+x)/(1-9x)

domain

\frac{9 + x}{1 - 9 x}

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}

f (x) = \frac{4 + 7 x}{x - 1}

f (x) = lo g_{10} (9 x^{2} + 30 x + 29)

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

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

f (x) = lo g_{e} (x^{2} - 1)

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