Name:Date: Period:Topic: Patterns and Linear FunctionsEssential Question: How can you represent and describe functions?
Warm-Up:
1. The average price for a game rental is about $5.99 per game. The table below represents the total cost of renting video games at a random store. Complete the following table for the missing values.

Write an expression to describe the pattern:
Complete the table below, identify the pattern, and write the appropriate expression.
Identify quantities in the pictures that vary in response to other quantities:
Vocabulary:
Independent Variable
• Inputs (Domain)
Dependent Variable
• Outputs (Range)
Functions
is a variable that provides the input values of a function
is a variable that provides the output values of a function
• the values of ‘x’ or independent variable
is a relation that assigns exactly one value in the range to eachvalue of the domain. (No Value in the DOMAIN can be repeated)
• the values of ‘y’ or dependent variable
