engineering mathematics MCQ #826

  1. Question 1

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

    • A) 6x² + 10x - 7
    • B) 6x + 10 - 7
    • C) 2x² + 5x - 7
    • D) 6x³ + 10x² - 7x

    Answer: 6x² + 10x - 7

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