(Section 1.3: Basic Graphs and Symmetry) 1.3.12 PART I: RECIPROCAL FUNCTION andPOWER FUNCTIONS WITH NEGATIVE, ODD POWERSLet fx()=1xorx±1. We callfa reciprocal function, because its output is the reciprocal (or multiplicative inverse) of the input. We will carefully construct the graph off. Let’s construct a table for x±1. x1 10 100 ±², or 1x1 1101100±0+• The 0+notation indicates an approachto 0 from greaternumbers, without reaching 0.The table suggests the following graph for
