SOL Review Materials
Patterns, Functions, and Algebra
Focus: Linear Relationships


The student will identify the domain, range, independent variable, or dependent variable in a given situation. 
Essential Knowledge and Skills 
  • Apply the following algebraic terms appropriately: domain, range, independent variable, and dependent variable.
  • Identify examples of domain, range, independent variable, and dependent variable.
  • Determine the domain of a function.
  • Determine the range of a function.
  • Determine the independent variable of a relationship.
  • Determine the dependent variable of a relationship.
Essential Understandings
  • What are the similarities and differences among the terms domain, range, independent variable and dependent variable? The value of the dependent variable changes as the independent variable changes. The domain is the set of all input values for the independent variable. The range is the set of all possible values for the dependent variable.

Explore Learning
  1. Introduction to Functions: Determine if a relation is a function using the mapping diagram, ordered pairs, or the graph of the relation. Drag arrows from the domain to the range, type in ordered pairs, or drag points to the graph to add inputs and outputs to the relation.

VDOE Interventions
  1. VDOE Algebra Readiness Curriculum Companion: Investigating Patterns, Functions, and Algebra - The lessons focus on algebraic reasoning. Students explore the relationships found in number patterns through arithmetic and geometric sequences using variables expressions. They use modeling to collect data, and they learn to record data so that they can see the relationship that exists among tables, graphs, words, and equations. (pdf)
