For a function of the form f%28x%29=ax%5E2%2Bbx%2Bc, the line of symmetry is the vertical line passing through the vertex. The x-coordinate of the vertex is given by %28-b%29%2F2a, so the equation of the line of symmetry is x=%28-b%29%2F2a

For your equation: a=-2 and b=11.

You should be able to take it from here.

f(x)=-2x^2+11x+7
find the line of symmetry of the given function.
------------------
line of symmetry is always x = -b/2a
--------------
Your Problem:
x = -11/(2*-2) = 11/4
That is the line of symmetry.
