Ready solution of the problem. The sorcerer of Arutyunov. Task number 123.

121 - 130. The function y = f (x) and two values of the argument x1 and x2 are given. It is required: 1) to determine whether the given function is continuous or discontinuous for each of these values of the argument; 2) in the case of discontinuity of the function, find its limits at the point of discontinuity on the left and on the right; 3) make a schematic drawing.

123. f (x) = 121 / x, x1 = 0, x2 = 2.
