The following data samples are given to train a neuron.

C$1$: $(-17,2\mathrm{.}6,4\mathrm{.}2),(1,-2,3),(2,12,-7)$

C$2$: $(20,1\mathrm{.}513),(8\mathrm{.}3,-21,-7\mathrm{.}5)$

We use gradient descent learning for training the neuron. Which of the following equations is the correct cost function?
