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

domain

f (x) = \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}

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