Evaluate the Function f(8) = cube root of x-8

$f (8) = \sqrt[3]{x - 8}$

Step 1

Replace the variable $x$ with $8$ in the expression.

$f (8) = \sqrt[3]{(8) - 8}$

Step 2

Simplify the result.

Subtract $8$ from $8$ .

$f (8) = \sqrt[3]{0}$

Rewrite $0$ as $0^{3}$ .

$f (8) = \sqrt[3]{0^{3}}$

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

$f (8) = 0$

The final answer is $0$ .

$0$
