Q3 of 96 Page 15

Mark the correct alternative in the following:

For the function the value of c for the Lagrange’s mean value theorem is




It shows that f(x) is continuous on 1, 3 and derivable on 1, 3.


So, both the conditions of Lagrange’s Theorem are satisfied.


Consequently, there exists c Є 1, 3 such that

























Hence, Є (1, 3) such that .


Hence, Option (B) is the answer.
