F(x)=(x-1)(x-2)(x-3) and a=0 b=4
F(x)=(x-1)(x-2)(x-3) and a=0 b=4-33 Solving x2x4 = 0 by Completing The Square Add 4 to both side of the equation x2x = 4 Now the clever bit Take the coefficient of x , which is 1 , divide by two, giving 1/2 , and finally square it giving 1/4 Add 1/4 to both sides of the equation On the right hand side we haveF (x) = (x1) (x2) (x3) , x ∈ 0,4, ∴ f (x) = x 3 6x 2 11x 6 As f (x) is a polynomial in x (1) f (x) is continuous on 0, 4 (2) f (x) is differentiable on (0, 4) Thus, all the conditions of LMVT are satisfied To verify LMVT we have to find c ∈ (0,4) such that
