Hello!

In order to use the MVT, the function must be continuous over the given interval.
![y = (x^(2) )/(4x)+4](https://img.qammunity.org/2021/formulas/mathematics/college/uaop62ovxv10lp4b55fagdelpayci11q7f.png)
Simplifies to:
![y = (x)/(4) + 4](https://img.qammunity.org/2021/formulas/mathematics/college/dk2df8skyc3ipw0hwp76gpttqxce3hn1f9.png)
This is a linear equation that is continuous on the interval (-∞, ∞), which means that it would also be continuous on the interval [-6, -2]. The MVT would apply to this function.
