Answer:
The derivative of a function must be equal to zero ( 0 ) if this condition is not met then a hypothesis is refuted
Explanation:
The conditions that must be satisfied to assure that a refutable hypothesis will be obtained by examining the structure of the FOC is
The derivative of a function must be equal to zero ( 0 ) if this condition is not met then a hypothesis is refuted
i.e. dy/dx w.r.t.x = 0 for FOC to be refutable
