I really dont know but if i did i would tell you and i will try and find out
f' = a(x-2)
f'(3) < 0, so a < 0
f' = 2-x
f = 2x - x^2/2 + c
or, how about
f(x) = 4x-x^2+c
(f(4)-f(0))/(4-0) = 0
so f(4) = f(0)
16-16+c = 0-0+c
works for any c, so let's use c=0
f(x) = 4x-x^2
f'(3) < 0, so a < 0
f' = 2-x
f = 2x - x^2/2 + c
or, how about
f(x) = 4x-x^2+c
(f(4)-f(0))/(4-0) = 0
so f(4) = f(0)
16-16+c = 0-0+c
works for any c, so let's use c=0
f(x) = 4x-x^2
