  1. Question 1

    Q1. If y = 2x³ + 5x² - 7x + 3, then dy/dx = ?

    • A) 6x² + 10x - 7
    • B) 6x² - 10x + 7
    • C) 6x² + 10x + 7
    • D) 6x² - 10x - 7

    Answer: 6x² + 10x - 7

    Explanation: Using the power rule for differentiation, if y = x^n, then dy/dx = nx^(n-1), and differentiating term by term.
