    The answer to your question is the letter A.

    Step-by-step explanation:

    Data

    y = x² + 10x + 26

    Factor the right side of the equation

    y - 26 = x² + 10x

    -Complete the perfect trinomial square

    y - 26 + (5) ² = x² + 10x + (5) ²

    -Simplify

    y - 26 + 25 = x² + 10x + 25

    y - 1 = (x + 5) ²

    Vertex = (-5, 1)

    The function given is a vertical parabola whose axis of symmetry goes through x = - 5
