Figure from the original question paper Graph of two sigmoid functions f(x) = 1/(1 + e^-(x+a)) and g(x) = 1/(1 + e^-(x+b)) plotted for x from -5 to 2 Which of the following is true? Scatter plot of dataset D1 in R^2 with + and - points and the dashed parabola x2 = x1^2, followed by the transformation (x1, x2) -> (x1^2, x2) and "Which of the following statements are true?"
