Is it A? If not could you please explain why not
Let F be a primitive off on interval (a,b). It's true that:
a) x is an inflectionary point of F = f(x) =
b) 220 is a local minimum point of F = f(xd=0
c) f(2) is a constant function → F(x) is constant
DF(x) ≤0, for all x &(a,b) ⇒ f is decreasing
in (a,b)
