Mathalicious: Scale Factor

Who should win extreme weight loss competitions?

In the TV game show The Biggest Loser, contestants compete to lose the greatest percent of body weight. While some praised the show as a helpful source of inspiration, others criticized it as an unrealistic and unhealthy example of how to lose weight.

In this lesson, students use linear functions and lines-of-best-fit to predict results from Season 8 of The Biggest Loser and discuss whether such examples of extreme weight loss are realistic and sustainable.
