Lessons for Topic 1.3
Average rate of change from a formulaEvaluating the rule at both ends of an interval and dividing the change in output by the width.Lesson
Average rate of change from a table or graphUsing two rows of a table to find the change in output divided by the change in input.Lesson
Average rate of changeHow much the output changes per unit of input across an interval, the slope of the line joining two points.Lesson
Constant rate of change and linear tablesA function is linear exactly when equal steps in the input always give equal steps in the output.Lesson
Linear, polynomial and exponential growth comparedLinear growth adds the same amount each step while exponential growth multiplies by the same factor.Lesson
Maximum, minimum and range of a quadratic functionThe vertex gives the largest output for a downward parabola and the smallest for an upward one.Lesson
