The volume of air in a person's lungs, as the person breathes in and out, can be modeled by a sine graph. A scientist is studying the differences in this volume for people at rest compared to people told to take a deep breath. When examining the graphs, should the scientist focus on the amplitude, period, or midline? Explain your choice.
Explain whether the scientist should focus on the amplitude, period, or midline when examining the graphs of lung volume.
Which function has a maximum -value of 4 and a midline of ?
