Answer:

Rate of change of the function, dC/dW = 3

Explanations:

Let the cost be represented as C

Let the wight be represented as W


\begin{gathered} (W_1,C_1)\text{ = (1, 3)} \\ (W_2,C_2)\text{ = (4, 12)} \end{gathered}

The rate of change of the function can be calculated using the formula:


\begin{gathered} (dC)/(dW)=\text{ }\frac{C_2-C_1_{}}{W_2-W_1} \\ (dC)/(dW)=\text{ }(12-3)/(4-1) \\ (dC)/(dW)=\text{ }(9)/(3) \\ (dC)/(dW)=\text{ 3} \end{gathered}
