Learners will develope a basic understanding of a function and explore different ways to represent functions.
The definition of a function is presented and explained using different representations. The idea of input and output is introduced. Learners will distinguish between functions and non-functions.
The idea of input and output is connected to domain and range. Learners identify given domain and range. Learners explain implied domain and range of groups of functions.
Student use graphing manipulatives to identify function notation given points on the graph of the function.
Applications of functions are introduced. Students are guided to discover how functions can help solve problems. These may be ideal as a group activity.
Formal assessment includes a quiz at the end of the module. The quiz includes questions on different representations of functions, identifying functions, and finding given and implied domain and range.
