domain of (7x)/(5x-4)

domain

\frac{7 x}{5 x - 4}

x < \frac{4}{5} or x > \frac{4}{5}

Interval Notation

(- \infty, \frac{4}{5}) \cup (\frac{4}{5}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{4}{5}

The function domain

x < \frac{4}{5} or x > \frac{4}{5}

\frac{4}{- 6 x ^{2} - 5 x - 1}

∣ x - 5 ∣

ln (\frac{1}{x + 3})

y = \frac{x ^{2} - 5 x + 6}{x - 4}

f (x) = \frac{2}{3 x ^{2}}

What is the domain of (7x)/(5x-4) ?
The domain of (7x)/(5x-4) is x< 4/5 \lor x> 4/5
