domain of f(x)=(8+x)/(1-8x)

domain

f (x) = \frac{8 + x}{1 - 8 x}

x < \frac{1}{8} or x > \frac{1}{8}

Interval Notation

(- \infty, \frac{1}{8}) \cup (\frac{1}{8}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{1}{8}

The function domain

x < \frac{1}{8} or x > \frac{1}{8}

What is the domain of f(x)=(8+x)/(1-8x) ?
The domain of f(x)=(8+x)/(1-8x) is x< 1/8 \lor x> 1/8
