domain of f(x)= x/(9x-8)

domain

f (x) = \frac{x}{9 x - 8}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = \frac{8}{9}

The function domain

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

10 x + 17 y = 12

f (x) = \frac{x + 5}{x ^{2} + x - 6}

f (x) = x^{3} + 9 x^{2} + 24 x

f (x, y) = 1 - x^{2}

f (x) = 3 x

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