domain of f(x)=(7x)/(5x-9)

domain

f (x) = \frac{7 x}{5 x - 9}

x < \frac{9}{5} or x > \frac{9}{5}

Interval Notation

(- \infty, \frac{9}{5}) \cup (\frac{9}{5}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{9}{5}

The function domain

x < \frac{9}{5} or x > \frac{9}{5}

\frac{( 8 x + 5 )}{4 x + 2}

- sin (2 t) + sin (t)

- x^{4} - x^{3} + 6 x^{2} + 4 x - 8

y = e^{- x} - 4

f (x) = x^{2} - 4 x - 21

What is the domain of f(x)=(7x)/(5x-9) ?
The domain of f(x)=(7x)/(5x-9) is x< 9/5 \lor x> 9/5
