Question

Consideremos a função custo C(x)= 0,02x³-0,4x²+200. Qual será o custo
marginal?

Answer 1

Resposta:

Para achar o custo marginal faça:

$\dfrac{\partial C}{\partial x}=\dfrac{\partial (0,02x^{3})}{\partial x}-\dfrac{\partial (0,4x^{2})}{\partial x}+\dfrac{\partial (200)}{\partial x}\\\\\\\dfrac{\partial C}{\partial x}=0,06x^{2}-0,8x$
