engineering mathematics MCQ #750

  1. Question 1

    Q1. If y = e^(2x + 1), then dy/dx = ?

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

    Answer: 2e^(2x + 1)

    Explanation: Using chain rule, dy/dx = d(e^(2x + 1))/dx = e^(2x + 1) * d(2x + 1)/dx = e^(2x + 1) * 2 = 2e^(2x + 1).
