Given: f(x)=x^(2/3)-1,[-8,8].

Rolle's Theorem does not apply to the function f(x) on the given interval because all 3 conditions of Rolle's Theorem will not be met.

The function f(x) is continuous on the closed interval [-8,8].

The function f(x) is not differentiable on the open interval (-8, 8). The function is not differentiable at x=0.

f(-8)=f(8)=3.

Because all 3 conditions are NOT met Rolle's Theorem does NOT apply.
