Another possibility is tikzfillbetween but does your code come from some automatic tool?

Because:

• you uselessly loaded pgf (it is already loaded by tikz)


• the scriptsize environment within the tikzpicture does nothing, use the option scale=..., instead


• the formulae of your line and your parabola are uselessly complicated (I've changed them)


• your color definitions are strange.

Another possibility is tikzfillbetween but does your code come from some automatic tool?

Because:

• you uselessly loaded pgf (it is already loaded by tikz)


• the scriptsize environment within the tikzpicture does nothing, use the option scale=..., instead


• the formulae of your line and your parabola are uselessly complicated (I've changed them)


• your color definitions are strange.
