(Type a simplified fraction.)
The equation of the line of symmetry is x=___.
(Type a simplified fraction.)
The maximum/minimum of f(x) is ___.

You can put this solution on YOUR website! f(x)=-2x^2+2x+5
.
x=-b/2a
=-2/-4
=1/2
The x-coordinate of the vertex is 1/2. Which is also the line of symmetry.
.
-2*.5^2+2*.5+5
=11/2
The y-coordinate of the vertex is 11/2 which is also the maximum.
