domain of (4x+9)/(3x-4)

domain

\frac{4 x + 9}{3 x - 4}

x < \frac{4}{3} or x > \frac{4}{3}

Interval Notation

(- \infty, \frac{4}{3}) \cup (\frac{4}{3}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{4}{3}

The function domain

x < \frac{4}{3} or x > \frac{4}{3}

f (x) = lo g_{10} (- x - 20)

f (x) = \frac{1}{1 - ∣ 2 x ∣}

\frac{2 x + 5}{x - 1}

f (x) = \frac{x ^{2} + 1}{x ^{2} - 16}

\frac{2}{t + 4}

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