domain of f(x)=(3x)/(4x-9)

domain

f (x) = \frac{3 x}{4 x - 9}

x < \frac{9}{4} or x > \frac{9}{4}

Interval Notation

(- \infty, \frac{9}{4}) \cup (\frac{9}{4}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{9}{4}

The function domain

x < \frac{9}{4} or x > \frac{9}{4}

f (x) = - ∣ x - 3 ∣ - 2

f (x) = t - 3

\frac{x ^{2} - 4 x + 4}{x ^{2} - 4}

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

g (x) = \frac{6 x ^{2} + x - 5}{3 x ^{2} - 7 x - 20}

What is the domain of f(x)=(3x)/(4x-9) ?
The domain of f(x)=(3x)/(4x-9) is x< 9/4 \lor x> 9/4
