Each graph is a translation of the graph of one of the basic functions y = x2, y = x3, y = 2x, or, Find the equation that defines each function. Then, using the concepts of increasing and decreasing functions discussed in Section 2.1, determine the largest open interval of the domain over which the function is (a) increasing and (b) decreasing
