Graph the quadratic functions y = -2x2 and y = -2x2 + 4 on a separate piece of paper. Using those graphs, compare and contrast the shape and position of the graphs. (3 points)

  • math -

    Y = -2x^2

    h = Xv = -B/2A = 0/-4 = 0.
    k = -2*0^2 = 0.
    V(0,0).

    Use the following points for graphing:

    Y = -2x^2.

    (x,y)
    (-2,-8)
    (-1,-2)
    V(0,0)
    (1,-2)
    (2,-8)

    Y = -2x^2 + 4.

    h = Xv = -B/2A = 0/-4 = 0.
    k = Yv = -2*0^2 + 4 = 4.
    V(0,4).

    (-2,-4)
    (-1,2)
    V(0,4)
    (1,2)
    (2,-4)
