domain of f(x)=(8x)/(9x-1)

domain

f (x) = \frac{8 x}{9 x - 1}

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}

(2, 5), (- 5, - 4)

(0, \frac{π}{2}), (π, - \frac{π}{2})

ln (cos (x)) tan (x) d x

f (x) = - 2 x

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