Graphs of solutions of the equation dydx y2 The graph y Cx
       Graphs of solutions of the equation dy/dx = y^2.  The graph y = Cx^4 for various values of C.  Show that y(x) = Cx^4 defines a one-parameter family of differentiable solutions of the differential equation xy\' = 4y (Fig. 1.1.9).  Show that  y(x) = {-x^4 if x  0  defines a differentiable solution of xy\' = 4y for all x, but is not of the form y(x) = Cx^4.  Given any two real numbers a and b, explain why-in contrast to the situation in part (c) of Problem 47-there exist infinitely many differentiable solutions of xy\' = 4y that all satisfy the condition y(a) = b.
