Relations and Functions.

10 lessons106 min5 simulations

This chapter builds functions from the ground up: ordered pairs, the Cartesian product of two sets, relations as subsets of that product, and functions as the relations in which every input has exactly one output. It then studies the standard real functions with their graphs, domains and ranges, and the arithmetic of combining functions, all of which calculus depends on.
