2.38.) The graph of the equation (x2 + y2 - 2x)2 = x2 + y2 is given in Figure 2.7.6. (a) Use a CAS, or straightforward algebra, to find four functions defined implicitly by this equation. By either method, it might help to start with the substitution Y = y?. (b) Use a graphing utility to obtain the graph of each function. (c) Give the domain of each function found in part (a). 13 FIGURE 2.7.6 Graph for Problem 34
