domain of (5x)/(7x-2)

domain

\frac{5 x}{7 x - 2}

x < \frac{2}{7} or x > \frac{2}{7}

Interval Notation

(- \infty, \frac{2}{7}) \cup (\frac{2}{7}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{2}{7}

The function domain

x < \frac{2}{7} or x > \frac{2}{7}

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

x^{2} + 16

f (x) = \frac{- 1}{x ^{2} - 36}

f (x) = - 2 x^{2} + 4 x - 3

f (x) = \frac{( - 1 )}{( x ^{2} - 36 )}

What is the domain of (5x)/(7x-2) ?
The domain of (5x)/(7x-2) is x< 2/7 \lor x> 2/7
