To develop basic skills in working with algebraic representations of rational functions. To experience statistical analysis in a real-world setting. To apply the concept of work in understanding our world. Students should have some exposure to functions with asymptotes. This activity can be used to introduce and apply methods of translations including vertical shifts, horizontal shifts, and stretching or compressing of functions.
Most students have some basic notion of work.
This notion may need to be clarified or made explicit. Each student needs activity sheets and a graphics calculator. Each group of three to four students needs shelled, whole, blanched peanuts and a meter stick. Different kinds of peanuts will produce different ranges of data. The data provided in the answers are based on a brand of oily blanched peanuts.
