domain of f(x)=(4-5x^3)^{-2}

domain

f (x) = (4 - 5 x^{3})^{- 2}

x < 3 \frac{4}{5} or x > 3 \frac{4}{5}

Interval Notation

(- \infty, 3 \frac{4}{5}) \cup (3 \frac{4}{5}, \infty)

Solution steps

Find undefined (singularity) points:

x = 3 \frac{4}{5}

The function domain

x < 3 \frac{4}{5} or x > 3 \frac{4}{5}

f (x) = \frac{9 x - 5}{x ^{2} - 9 x + 8}

\frac{x ^{2} - 2 x}{x + 3}

y = 3 t^{2} - 2 t + 1

\frac{x ^{2} + 2 x - 8}{x ^{2} + 5 x + 4}

What is the domain of f(x)=(4-5x^3)^{-2} ?
The domain of f(x)=(4-5x^3)^{-2} is x<\sqrt[3]{4/5}\lor x>\sqrt[3]{4/5}
