(Section 1.5: Piecewise-Defined Functions; Limits and Continuity in Calculus) 1.5.5 Example 3 (Graphing a Piecewise-Defined Function with a Removable Discontinuity)Graphf, if fx()=x+3,x±37,x=3²³´. § Solution• We graph the line y=x+3, except we leave a holeat the point 3, 6, since 3 is deletedfrom the subdomain of the top rule. • The bottom rule defines f3to be 7, so we plot the point 3, 7.
