3. We want to study the behavior of the function \( f(x) \) whose derivative is equal to itself. The interactive SageMath app below starts with \( f(0) = 1 \) and a given number of steps (between 0 and 1) and approximates the values of \( f(1) \), \( f(2) \), \( f(3) \), and \( f(4) \). Use this app to answer the questions in your lab report.
