Question 2 Examine if Rolleโs theorem is applicable to the functions. Can you say some thing about the converse of Rolleโs theorem from this function? (๐) ๐ (๐ฅ) = [๐ฅ] ๐๐๐ ๐ฅ โ [5, 9]Greatest Integer less than equal to ๐ฅ ๐ (๐ฅ) =[๐ฅ] is not continuous & differentiable โ Condition of Rolleโs Theorem is not satisfied. Therefore, Rolleโs Theorem is not applicable .
