1. Name: Date: Period: Topic: Patterns and Linear Functions Essential 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. xy 1$5.99 2$11.98 3 4 5 6 7 Write an expression to describe the pattern:

2. Complete the table below, identify the pattern, and write the appropriate expression.

3. Identify quantities in the pictures that vary in response to other quantities:

4. 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 each value of the domain. (No Value in the DOMAIN can be repeated) the values of ‘y’ or dependent variable xy 12 24 36 48 xy 12 24 26 48 Yes Not (3, 4), (5, 6), (7, 8) (3, 4), (3, 6), (7, 8)

5. Linear Functions a function whose graph is a nonvertical line. Vocabulary: These are functions, but Non-linear functions
