  1. Question 1

    Q1. If y = 2x³ + 5x² - 3x + 1, then dy/dx = ?

    • A) 6x² + 10x - 3
    • B) 6x² - 10x + 3
    • C) 2x² + 5x - 3
    • D) 6x³ + 10x² - 3x

    Answer: 6x² + 10x - 3

    Explanation: Using the power rule for differentiation, which states that if y = x^n, then dy/dx = nx^(n-1), we differentiate term by term.
