A software program can show a user how far he or she is from a location on a map. Zadie is walking in a straight line down her street. For any time [math]t[/math], in seconds, her distance [math]d[/math] from her home, in feet, can be represented by the function [math]d = 4 \mid{t − 20}\mid[/math]. Create a graph to show Zadie’s distance from her house. Which point on the graph shows when Zadie has reached her house?
