Illustrative Math - Algebra 1 - Unit 6 - Lesson 2

Each expression represents the total number of dots in a pattern where n represents the step number.Select all the expressions that represent a quadratic relationship between the step number and the total number of dots. (If you get stuck, consider sketching the first few steps of each pattern as described by the expression.)
