Equivalent expressions of functions Emphasizing information using correspondence rules Four graphs of functions are displayed below, as well as three kinds of information about each graph: the point of intersection with the x-axis, the point of intersection with the y-axis, and a point traversed by the graph. Also shown are three forms of correspondence rules. In each figure, change the given correspondence rules to fit the given graph in such a way that the rules emphasize the information on the point you choose to emphasize. intersection with x-axis intersection with y-axis a point on the graph 1 step trace 2 step trace 3 step trace 4 step trace
