2. Given a two-input neuron with a weight matrix w -11, -2] and an input vector x [-3, 5], an output of 0.75 is required. a. Do you suppose that there is combination of bias and activation function that can allow this? b. Can this be done with a bias of zero? c. What are the appropriate activation functions that can be used? d. Can you find another weight matrix that will do the job for the activation function that you have selected? (25 points)
