Chapter 4 - An Introduction to Functions - 4-1 Using Graphs to Relate Two Quantities - Lesson Check: 4

Answer

A real-world example of the graph in number 3 would be biking. Where the x-axis is time and the y-axis is speed. In "A", the person is biking fast to get to his destination since he is in a rush, shown as the graph goes up. In "B", the bike is slowing down as it reaches a stoplight, shown as the line decreases. In "C" the speed is constant due to the biker because he is conserving energy. In "D", the bike is making a sharp decrease in speed because another biker cut him off. Finally, "E" shows a slower decrease in speed because he is arriving at the destination.
