Learning goals: Learning Goals • Understand that a function has one and only one output for each allowable input. (Lesson 2) • Represent a function with an equation. (Lesson 4) • Understand that if a rate of change is positive over an interval, the function is increasing over that interval. If it is negative over an interval, the function is decreasing over that interval. (Lesson 5) • Compare inputs and outputs of functions that are represented in different ways. (Lesson 7) • Decide when it is reasonable or not to model a time series with a linear function. (Lesson 8) • Calculate different rates of change of a piecewise linear function using a graph, and interpret rates of change in context. (Lesson 9) • Calculate the volumes of cylinders. (Lesson 11) • Recognize that the volume of a cone is one-third the volume of a cylinder with the same base and height. (Lesson 13) • Find one dimension of a cylinder or cone given its volume and another dimension. (Lesson 14) • Develop and use a formula for the volume of a sphere. (Lesson 15)
