Document Summary

Econ 1530 lecture 1 notes shifting graphs. Its graph, which is shown in figure below, is obtained by moving the graph of two units to the left. It is obtained by reflecting the graph of y = x about the y-axis: general rules for shifting the graph of y = f (x): If y = f (x) is replaced by y = f (x) + c, the graph is moved upwards by c units if c > If y = f (x) is replaced by y = f (x + c), the graph is moved c units to the left if c > 0 (to the right if c < 0). If y = f (x) is replaced by y = cf (x), the graph is stretched vertically if c > 0 (stretched vertically and reflected about the x-axis if c < 0).
