CHA-4.A—Interpret the meaning of areas associated with the graph of a rate of change in context
CHA-4.A Interpret the meaning of areas associated with the graph of a rate of change in context.
CHA-4.A.1 The area of the region between the graph of a rate of change function and the x axis gives the accumulation of change.
CHA-4.A.2 In some cases, accumulation of change can be evaluated by using geometry.
CHA-4.A.3 If a rate of change is positive (negative) over an interval, then the accumulated change is positive (negative).
CHA-4.A.4 The unit for the area of a region defined by rate of change is the unit for the rate of change multiplied by the unit for the independent variable.
Enduring understanding CHA-4: Definite integrals allow us to solve problems involving the accumulation of change over an interval.
