Description
What It Is:
This is a math worksheet focusing on functions and ordered pairs. The worksheet is divided into two sections. Section A presents sets of ordered pairs, and the task is to state whether each set represents a function. Section B presents three coordinate plane graphs with plotted points, and the task is to determine if each graph represents a function.
Grade Level Suitability:
This worksheet is most suitable for 8th-grade or 9th-grade students, or Algebra 1 students. It requires an understanding of coordinate planes, ordered pairs, and the definition of a function.
Why Use It:
This worksheet helps students practice identifying functions from sets of ordered pairs and from graphical representations. It reinforces the understanding of the definition of a function, specifically the concept that each input (x-value) can only have one output (y-value).
How to Use It:
For Section A, students should examine each set of ordered pairs and determine if any x-value is repeated with different y-values. If there are no repeated x-values, then it is a function. For Section B, students can use the vertical line test on each graph. If a vertical line intersects the graph at more than one point, then it is not a function. Students should write their answers on the lines provided.
Target Users:
The target users are middle school or high school students learning about functions and relations in algebra or pre-algebra classes. It is also suitable for students who need extra practice with this concept.
