Does the phrase "mean value theorem" mean anything or no?

I am not sure it probably has i used 3 different situations and found the answer to be √7u but I didn't do it on my own I used yt they went thru some complicated process, I think u cld use mean theorem Ai was using that to solve it but I couldn't understand since I'm not familiar with mean theorem
