Question

qual é a derivada y=(x-2)²​

Answer 1

$\dfrac{\partial y}{\partial x} = \dfrac{\partial (x-2)^2}{\partial x}$

$\dfrac{\partial y}{\partial x} = 2 \cdot (x - 2) \cdot \dfrac{\partial (x-2)}{\partial x}$

$\dfrac{\partial y}{\partial x} = 2 \cdot (x - 2) \cdot 1$

$\dfrac{\partial y}{\partial x} = 2 \cdot (x - 2)$

$\boxed{\dfrac{\partial y}{\partial x} = 2 \cdot x - 4}$
