Let {{MATH_37}} be a function. If the point {{MATH_38}} is on the graph of {{MATH_39}}, what point must be the the graph of {{MATH_40}}? {{CMD_41}} {{MATH_42}} {{CMD_43}} {{CMD_44}} Since {{MATH_45}}, we must have {{MATH_46}}, so {{MATH_47}}. Thus {{MATH_48}} is on the graph of {{MATH_49}}. This is a general rule. If {{MATH_50}} is on the graph of {{MATH_51}}, then {{MATH_52}} will be on the graph of {{MATH_53}}. {{CMD_54}} {{CMD_55}}
