Keywordsvertex, vertical parabolawe know that the equation of a parabola vertical in vertex form is equal to, contains(h,k) is the vertexIf -----> the parabola opens up (vertex is a minimum)If -----> the parabola opens down (vertex is a maximum)In this problem we haveso the parabola opens down (vertex is a maximum)to Convert the vertex formGroup terms that contain the same variable, and move the constant on the opposite side of the equationFactor the leading coefficient to Complete the square. Remember to balance the equation by adding the same constant to each side.Rewrite as a perfect squaresThe vertex is the point thereforethe answer is the option
