In collections Einführung Funktionsbegriff
① This interactive example for middle school students demonstrates how to use a function's value table to understand functional relationships and switch between function equations, tables, and graphs. ② The core mathematical concepts are the multiple representations of real functions—equation, table, and graph—and the transitions between them, fostering intuitive understanding of functions. ③ Cons
