axis of symmetry for y = 4x^2 + 1/2x + 3
---------------
It's x = -b/2a
x = -(1/2)/8
x = -1/16

y = 4x^2 + 1/2x + 3
:
The axis of symmetry for this parabola (it curves upward) is the x coordinate of the vertex
:
x = -b / (2*a) = -(1/2) / (2*4) = -1/16
:
****************************
axis of symmetry is x = -1/16
