Question 636699: I would appreciate your help on this: f(x)=-2x^2+2x+6. Find the vertex, the line of symmetry, the maximum or minimum value of the quadratic function, and graph the function.
This is what I have so far.
x coordinate of the vertex is 1/2
the y-coordinate of the vertex is_____
the equation of the line of symmetry is x=
The maximum /minimum of f(x)is_____
The value f(1/2)=13/2 is maximum

---------

Now plug this back into equation

This is y-co-ordinate of vertex
There is a maximum at ( 1/2. 13/2 )
is equation of line of symmetry

----------------
Here's the plot:
