vertex = (1/2,5/2) x= 1 + or - square root of 5-2y all over 2

We are given this equation


y=-2x^(2) +2x+2

The vertex form is given by:


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

Now let us try to convert our equation into vertex form:


y=-2x^(2) +2x+2

Vertex form is given by:


y=-2(x-0.5)^(2) +2.5

comparing our equation with vertex form ,

The vertex (h,k) is (0.5, 2.5)

Next we have to find y when x=6, plugging x as 6 in the given equation,


y=-2(6)^(2) +2(6)+2

y=-58

So at x=6, y=-58.
