  1. Question 1

    Q1. If y = x⁴ - 4x³ + 6x² - 4x + 1, then d²y/dx² = ?

    • A) 12x² - 24x + 12
    • B) 12x² + 24x + 12
    • C) 4x³ - 12x² + 12x - 4
    • D) 4x³ + 12x² + 12x + 4

    Answer: 12x² - 24x + 12

    Explanation: First, find dy/dx = 4x³ - 12x² + 12x - 4, then d²y/dx² = 12x² - 24x + 12, differentiating again.
