Consider the functions f1(x) = x, f2(x) = x, if x 0, x, if x < 0. (a) Show that f2 is not in C1(,). (b) Show that{ f1, f2}is linearly dependent on the intervals(, 0) and [0,), while it is linearly independent on the interval (,). Justify your results by making a sketch showing both of the functions.
