A value of c according to the Lagrange's mean value theorem for f(x)=(x-1)(x-2)(x-3) in [0,4] is
Options
- A2+ 2 3
- B2- 16 3
- C1+ 5 4
- D2+ 8 3
Correct answer
A. 2+ 2 3
Step-by-step solution
f(x)=(x-1)(x-2)(x-3) in [0,4] By lagrange's mean value theorem aligned & f^ (c)= f(4)-f(0) 4-0 & (c-1)(c-2)+(c-1)(c-3)+(c-2)(c-3)= 6+6 4 & 3 c^2-12 c+8=0 c=2 48 6 =2 2 3 aligned
