engineering mathematics MCQ #672

  1. Question 1

    Q1. If y = e^(x² + 2x), then dy/dx = ?

    • A) e^(x² + 2x) (2x + 2)
    • B) e^(x² + 2x) (x + 2)
    • C) (2x + 2)e^(x²)
    • D) (x + 1)e^(x² + 2x)

    Answer: e^(x² + 2x) (2x + 2)

    Explanation: Using chain rule, dy/dx = e^(x² + 2x) * d(x² + 2x)/dx = e^(x² + 2x) (2x + 2).
