domain of (x+1)/(8x-9)

domain

\frac{x + 1}{8 x - 9}

x < \frac{9}{8} or x > \frac{9}{8}

Interval Notation

(- \infty, \frac{9}{8}) \cup (\frac{9}{8}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{9}{8}

The function domain

x < \frac{9}{8} or x > \frac{9}{8}

\frac{1}{3} (x - 4)^{2} + 2

U (x) = 12 x - 2148

- x^{4} + x^{2}

\frac{ln ( x )}{x - 3}

- \frac{3}{4 x}

What is the domain of (x+1)/(8x-9) ?
The domain of (x+1)/(8x-9) is x< 9/8 \lor x> 9/8
