As another example, consider the single-valued function 7/ = 5 .i* — 6 — or. (1) The following is a table of… … Fig. 27 38 GRAPHIC REPRESENTATION [Chap. III. respect to a line parallel to the F-axis and passing through thepoint (f, 0). The symmetry is also shown, without plotting, by solvingequation (1) for x. Thus, x = ^± Vi-y, (2) and therefore, for a given value of 7j, x has two values representedby…
