### Section 1.2 Explore, Prove, Question, Conjecture

Section 1.2 Explore, Prove, Question, Conjecture

**You will apply the investigative process as you ask questions and make and test predictions. You will represent a pattern of growth using tables, graphs, and equations, and you will make connections between expressions and geometric models. You will identify and describe important features of graphs. **
