$f (- 208) = - 6$
$f (8) = 0$

To evaluate $f (x)$ just substitute $x$ in $f$ expression...

$f (x) = root(3) {x - 8} rArr f (- 208) = root(3) {- 208 - 8} = root(3) {- 216} = root(3) {(- 6)^3} = - 6$

$f (x) = root(3) {x - 8} rArr f (8) = root(3) {8 - 8} = root(3) 0 = 0$

Given f(x)=root3(x-8)f(x)=root3(x-8) how do you find f(-208) and f(8)?
