Question:
Consider the following functions defined on piecewise domains:
j-x, x<0 iz 2
+ l, x< 0 fl{x) = W, *>0'
h{x) = Ì3X, *>0 '
h{x)~-
3 2 In other cases, one should define an integral by considering the value of the function at the beginning of each time bucket. A notable case occurs in financial engineering models, where the so-called Ito stochastic integral is extensively used. In fact, there are many kinds of integrals, but this is way beyond the scope of this book. See, e.g., Ref. [2] for an elementary introduction to such models.
For each function, indicate whether it is continuous and differentiable at the point of transition between each portion of the domain.
