Learning Paths
Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Chapter 1Contains Standard content
Graphs of Functions, Composite and Inverse Functions, Relations and Functions, Functional Equations, Sets and Intervals, Functions as Models of Data, Counting Functions
A taxi fare depends on the distance. The height of a ball depends on the time. A temperature in kelvin depends on a temperature in celsius. In each case, one number decides another, and mathematics has one word for this: a function. In this chapter we start from sets and relations, and we build the idea of a function with care. Then we draw functions, move and stretch their graphs, combine them, and undo them with the inverse. Python draws the graphs and checks our answers.
