Identify the vertex and the axis of symmetry of the graph functio
y=3(x+2)^2-3

Could someone please help me

  • algebra -

    as you should know, the parabola

    y = a(x-h)^2 + k

    has vertex at (h,k) and axis x=h.

    So, just read them off from your equation. Just be sure to make it fir the format exactly. Your equation is

    y = 2(x-(-2)) + (-3), so h = -2 and k = -3

    vertex: (-2,-3)
    axis: x = -2

    Oh thank you for explaining
