Correct Answer - Option 2 : 24x - 6

**Concept:**

Formula used:

If f(x) = xn, then f'(x) = n xn - 1

**Calculation:**

**Given:**

f(x) = 4x3 - 3x2 + 5

Differentiation with respect to x, we get

f'(x) = 4 × 3 × x^{2} - 3 × 2 × x

f'(x) = 12x^{2} - 6x

Again, Differentiation with respect to x

⇒ f"(x) = 24x - 6** **
