domain of f(x)=(-8-2x)/(5x-9)

domain

f (x) = \frac{- 8 - 2 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}

f (x) = x^{3} - 8 x + 3

y = 3 x + 4

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

f (x) = \frac{4}{x - 6} + \frac{4}{x - 1}

f (x) = 8 x^{- \frac{29}{12}}, x > 0

What is the domain of f(x)=(-8-2x)/(5x-9) ?
The domain of f(x)=(-8-2x)/(5x-9) is x< 9/5 \lor x> 9/5
