For the function given below, which statements concerning Rolle's theorem are true?

$f(x)=\frac{4x3}{x^2-x-12}$ over $-9,\frac{6}{11}$

Select all that apply:

Rolle's theorem does not apply because $f$ is not continuous on the closed interval $-9,\frac{6}{}.$

Rolle's theorem does not apply because $f$ is not differentiable on the open interval $(-9,\frac{6}{}).$

Rolle's theorem does not apply because $f(-9)f(\frac{6}{}).$

All three criteria for Rolle's theorem hold, so Rolle's theorem can be used.
