The function f(x) implemented by the MLP seems to be a non-linear function that maps the input x to a output value. The function seems to have two different regimes. For input values x between -2 and 2, the function seems to be linear with a slope of approximately 0.1. Outside of this interval, the function seems to have a different slope, approximately -0.5. The function also seems to have an offset of approximately -0.05.
