Chapter Two
2.1 Learning Targets
� Links quadratic equations to their graphs (parabolas)
� Graphs quadratic equations in the form y=ax^2 and identifies lines of symmetry and vertices
� Identifies quadratic relations from graphs, tables, and equations
2.2 Learning Targets
� Understand the effect of a, b, and c on the graphs of parabolas of the form y=ax^2+bx+c
� Uses quadratic equations and graphs to analyze the motion of projectiles
� Distinguishes between quadratic relationships and other types of relationships, such as cubics
2. 3 Learning Targets
� Understands the relationship between x and y in equations of the form xy = c, where c is a constant
� Graphs equations of the form xy = c or y = c/x where c is a constant
� Describes the behavior of y when x gets close to 0 or far from 0
� Understands the connection between inverse proportions and reciprocals
� Understands graphs of equations in the form xy = c, (x+c)y=1, and x(y-c)=1
2. 4 Learning Targets
� Forms conjectures about relationships
� Understands what it means to prove that a conjecture is true
� Analyzes arguments to see if they must always be true, using counterexamples when appropriate
