Find the vertex of this parabola: y=-x^2+2x-7

y = - x2 + 2x-7 y = - x2 + 2x-7 Complete the square on the right side of the equation. Tap for more steps ... - (x-1) 2 - 6 - (x-1) 2 - 6 Reorder the right side of the equation to match the vertex form of a parabola. y = - (x-1) 2 - 6 y = - (x-1) 2 - 6 Use the vertex form, y=a (x-h) 2 + k y=a (x-h) 2 + k, to determine the values of aa, hh, and kk. a=-1 a=-1 h=1 h=1 k=-6 k=-6 Find the vertex (h, k) (h, k).
