domain of f(x)=(18x^2-8)/(12x-8)

domain

f (x) = \frac{18 x ^{2} - 8}{12 x - 8}

x < \frac{2}{3} or x > \frac{2}{3}

Interval Notation

(- \infty, \frac{2}{3}) \cup (\frac{2}{3}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{2}{3}

The function domain

x < \frac{2}{3} or x > \frac{2}{3}

f (x) = 4 - x^{2} + x^{2} - 3 x

f (x) = x^{3} e^{x}

y = \frac{1}{x + 5}

f (x) = 8 - x

3 - x

What is the domain of f(x)=(18x^2-8)/(12x-8) ?
The domain of f(x)=(18x^2-8)/(12x-8) is x< 2/3 \lor x> 2/3
