What are the axes of symmetry in the graphs of the equations -2x^2 and -2x^2 + 4? I think the vertices are (0,0) and (0,4).

    You talk about equations, but show no equation.
    You must have meant the equations to be
    y = -2x^2 and y = -2x^2 + 4

    You are asking for the axes of symmetry but instead state the vertices.
    You were correct that the vertices are (0,0) and (0,4) respectively.

    so the axes of symmetry are x = 0 for both of them,
    that is, the axis of symmetry is the y-axis

    Thank you. Yes, I meant to put the y in there. Are the x-intercepts 0 and 4, respectively?

  • Math -

    I mean 0 for -2x^2. Sorry about the 4, I didn't mean to put that.

  • Math -

    yes , the x-intercepts are 0 and 4, respectively

    confused about your second reply, the vertices are indeed (0,0) and (0,4)

    <<I mean 0 for -2x^2. Sorry about the 4, I didn't mean to put that. >> , don't even know what that is supposed to say.

    see,
