Odd question. If you mean that in both cases y is a function of x, then the
first case is a straight line (for constant a), and the second one is a Sqrt
type curve plus a linear component. Plot both with different arbitrary
values of a, b and c. I see no relationship whatsoever, save for the fact
that both share(presumably) the same constant a. Perhaps you'd care to
explain what is your problem?
