Answer & Solution

Correct Answer

(B) 201864037-3201840372018201940372019

Step-by-step Solution

Detailed explanation

The given function is f(x)=(x-3)2018(x-2)2019, x∈ℝ. Differentiating w.r.t. x we get, f'x=x-32017x-220182018x-2+2019x-3 ⇒f'x=x-320174037x-22018x-100934037 Using rate of change of f'x, we can conclude that there is a local maxima at x=100934037.…
