Information
Description
What It Is:
This is an algebra worksheet focused on relations and functions. It includes exercises where students determine if a given relation, presented as a set of ordered pairs, is a function. Students are instructed to use a mapping diagram and explain their answer. The worksheet also presents four graphs and asks students to identify which of them are NOT functions.
Grade Level Suitability:
This worksheet is suitable for grades 8-10, typically Algebra 1 or introductory Algebra 2. The concepts of relations, functions, and their graphical representation are typically introduced in these grade levels.
Why Use It:
This worksheet helps students understand the definition of a function and practice identifying functions from sets of ordered pairs and from graphs. It reinforces the vertical line test for identifying non-functions graphically and encourages students to explain their reasoning, promoting deeper understanding.
How to Use It:
Students should first review the definition of a function. For the first two problems, they should create mapping diagrams to visualize the relations and determine if each input has only one output. They then write their answer (yes/no) and explain their reasoning. For the graph problems, students apply the vertical line test to each graph and identify the graphs that are not functions.
Target Users:
The target users are students learning about relations and functions in an Algebra 1 or Algebra 2 course. It can also be used for review by students who need to reinforce these concepts.
