domain of f(x)=(9x)/(4x-1)

domain

f (x) = \frac{9 x}{4 x - 1}

x < \frac{1}{4} or x > \frac{1}{4}

Interval Notation

(- \infty, \frac{1}{4}) \cup (\frac{1}{4}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{1}{4}

The function domain

x < \frac{1}{4} or x > \frac{1}{4}

f (x) = - 0.0625 t^{2} + 3 t - 20

\frac{x + 10}{x ^{2} - 100}

6 - 2 x

\frac{9 - x ^{2}}{3 x - 1}

ln (x^{2} - 4) + π

What is the domain of f(x)=(9x)/(4x-1) ?
The domain of f(x)=(9x)/(4x-1) is x< 1/4 \lor x> 1/4
