Question Which function has a vertex at the origin? f(x) = (x + 4)²2 f(x) = x(x-4) f(x) = (x-4)(x + 4) f(x) = -x²

Answer: f(x) = -x² Step-by-step explanation: Writing f(x) = -x² in vertex form gives f(x)=-(x-0)^2+0 which shows that the vertex (h,k) is at (0,0) The other equations written in vertex form do not have (h,k) = (0,0) Reply
