A neuron with 4 inputs has the weight vector w = [1, 2, 3, 4]^T and a bias = 0 (zero).
The activation function is linear, where the constant of proportionality equals 2 - that is, the activation function is given by f(net) = 2 × net.
If the input vector is x = [4, 8, 5, 6]^T then determine the output of the neuron.Show your work.
