Body: <p>I have the following problem, which I am unable to solve.</p>
  <blockquote>
  <p>A neural network with the following structure is given: 1 input neuron, 4 elements in the hidden layer, 1 output neuron.</p>
  <p>The output neuron is bipolar, the neurons in the hidden layer are linear.</p>
  <p>The weights between the input neuron and the neurons in the hidden layer have the following values: <span class="math-container">$w_{11} = -3, w_{12} = 2, w_{13} = -1, w_{14} = 0.5$</span>, while between neurons in the hidden layer and the starting neuron:: <span class="math-container">$w_{21} = +2, w_{22} = -0.5, w_{23} = -3, w_{24} = +1$</span> (no threshold input in both layers).</p>
  <p>What will the network response be like if the number 3 is given to the input neuron?</p>
