1.1 Using Qualitative Graphs to Describe Situations The Spring SaleLorem Ipsum Dolor Sit Amet Recall, in your earlier math career you learned about graphs, dealing with the coordinate plane. Below is a graph with some essential mathematical graphing concepts. Now lets consider, the authentic approach; or how this would relate to a real world situation. àฏSome hot coffee is poured into a cup at room temperature. Let F be the temperature in (degrees Farenheit) of the coffee and t be the time (in minutes) that have gone by since the coffee was poured. What do you think this graph would look like? Well, lets consider two terms: the independent and dependent variables. Which is which? Does the temperature of the coffee effect the time? Or does the time affect the temperature? Yes, I would agree, the amount of time affects the temperature. Therefore, the independent variable is the time. However, the only way that the temperature (dependent variable can be affected is if time passes. We can also
