  1. Question 1

    Q1. The vertex of the parabola y = x² + 2x + 1 is

    • A) (-1, 0)
    • B) (1, 0)
    • C) (0, 1)
    • D) (-1, 1)

    Answer: (-1, 0)

    Explanation: Using the vertex form y = a(x - h)² + k, where (h, k) is the vertex, completing the square gives y = (x + 1)², so vertex is (-1, 0).
