Guided Notes
Key concepts students will learn:
- •
In math, a function relates or connects one set to another set in a particular way, where a set is a group or collection of things.
- •
The input set of a function is called the domain, and the output set is called the range; these can be shown in a function table.
- •
A function must produce only one output value for each input value; this can be tested visually using the vertical line test.
