urgent math

without graphing, find the vertex, the azis of symemtry, and the maximum value or the minium value.

asked by Anne
  1. sorry i forgot to put the problem. here it is:
    f(x)=4(x+5)^2-6

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

    has vertex at (h,k).

    Naturally, the max/min is at the vertex and the vertex is on the axis of symmetry.
