Answer & Solution

Correct Answer

(C) \((A)-(I I I),(B)-(I V),(C)-(I),(D)-(I I)\)

Step-by-step Solution

Detailed explanation

(A) \( \frac{dy}{dx} = 3x^2-1 \) \( \left.\frac{dy}{dx}\right|_{x=2} = 3(2)^2-1 = 11 \) (B) \( \frac{dy}{dx} = 2(x-2) \) \( \left.\frac{dy}{dx}\right|_{x=2} = 2(2-2) = 0 \) (C) \( \frac{dy}{dx} = 4x \) \( \left.\frac{dy}{dx}\right|_{x=2} = 4(2) = 8 \) (D)…
