Outcomes

12F.D.1.1

Gather, interpret, and describe information about real-world applications of rates of change, and recognize different ways of representing rates of change

12F.D.1.2

Recognize that the rate of change for a function is a comparison of changes in the dependent variable to changes in the independent variable, and distinguish situations in which the rate of change is zero, constant, or changing by examining applications, including those arising from real-world situations
