put function in standard form

f(x)=-4x^2-32x+9

  • Calculus -

    There are many "standard forms". One of which is f(x)=a(x-h)²+k
    where (h,k) is the position of the vertex, and a is a constant.

    This can be achieved by completing the square of
    f(x)=-4x^2-32x+9
    =-4(x²+8x-9/4)
    =-4(x+4)²+4*4²+9/4
    =-4(x+4)²+265/4
