1 Answer

  • Answer:

    A. y = –x^2 + 4

    Step-by-step explanation:

    Find the vertex form.

    y = − ( x + 0 ) 2 + 4

    Graph the parabola using the direction, vertex, focus, and axis of symmetry.

    Direction: Opens Down

    Vertex:  

    ( 0 , 4 )

    Focus:  

    ( 0 , 15 /4 )

    Axis of Symmetry:  

    x = 0

    Directrix:
