Evaluate Using the Given Value f(-123) = cube root of -123-2

$f (- 123) = \sqrt[3]{- 123 - 2}$

Subtract $2$ from $- 123$ .

$f (- 123) = \sqrt[3]{- 125}$

Rewrite $- 125$ as ${(- 5)}^{3}$ .

$f (- 123) = \sqrt[3]{{(- 5)}^{3}}$

Pull terms out from under the radical, assuming real numbers.

$f (- 123) = - 5$

Evaluate Using the Given Value f(-123) = cube root of -123-2
