Definition 1. A function f(x) defined on (-L, L] is called piece-wise continuous if there are finitely many points xo =-L < x1 < x2 < < xn-L such that f is continuous on (xi, i+1) and so that the limits lim f(z) and lim f(x) both crist for each a,. To save space we write lin. f(x) = f(zi-) ェ→z, lim, f(x) = f(zit), ェ→ Sub-problem 5. Let f(x)-x on (-2,-1), f(x) = 1 on (-1,0) and f(x)--z on...
