domain of f(x)= x/(9x-7)

domain

f (x) = \frac{x}{9 x - 7}

x < \frac{7}{9} or x > \frac{7}{9}

Interval Notation

(- \infty, \frac{7}{9}) \cup (\frac{7}{9}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{7}{9}

The function domain

x < \frac{7}{9} or x > \frac{7}{9}

f (x) = \frac{1}{x ^{2} - 10 x + 25}

e^{x - 1} + 2

x 4 - x

(- 9, 14), (1, 10)

f (x) = x + 8

What is the domain of f(x)= x/(9x-7) ?
The domain of f(x)= x/(9x-7) is x< 7/9 \lor x> 7/9
