APCALC-BNX1FN

For which of the following functions does the Mean Value Theorem apply on the given interval?

I.$ f\left( x \right) =\cfrac { 1 }{ { x }^{ 2 }-1 } \quad \text{ on the interval } [-2,2]$II.$ g\left( x \right) ={ x }^{ \frac{2}{3} } \quad \text{on the interval }[1,4]$III.$h\left( x \right) ={ 2x }^{ 3 }+{ x }^{ 2 }-3 \quad \text{on the interval } [-3,1]$
