domain of (x^2-81)/(3x-8)

domain

\frac{x ^{2} - 81}{3 x - 8}

x < \frac{8}{3} or x > \frac{8}{3}

Interval Notation

(- \infty, \frac{8}{3}) \cup (\frac{8}{3}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{8}{3}

The function domain

x < \frac{8}{3} or x > \frac{8}{3}

f (x) = ln ∣ x + 2 ∣

- \frac{4}{5} x + 1

y = ln (40000 - x^{2}) + sin (x^{100})

\frac{3 x}{5 x - 8}

f (x) = lo g_{5} (2 x + 9) - 2

What is the domain of (x^2-81)/(3x-8) ?
The domain of (x^2-81)/(3x-8) is x< 8/3 \lor x> 8/3
