  2. Homework: Textbook- Read 546 - 549 Do: P. 549 -552: 1 – 4, 5, 8, 11, 14, 17, 21, 24, 48, 34-35 Objective: SWBAT… To graph quadratic function of the form y = ax2 and y = ax2 + c There are 6 children playing in a playground . Is the number of children playing a constant or a variable quantity? Consider The # of children is a variable quantity because it will change. What other variables might affect the number of children at the playground? Time of day; temperature… • quantity of children • Time of day • temperature What are the variables in the playground scenario?

Homework: Textbook- Read 546 - 549 Do: P. 549 -552: 1 – 4, 5, 8, 11, 14, 17, 21, 24, 48, 34-35 Objective: SWBAT… To graph quadratic function of the form y = ax2 and y = ax2 + c Definitions A variable whose value depends on the value of another variable. It changes in response to another variable. Also called OUTPUTS Dependent Variable Independent Variable The variable that changes another variable. Also called INPUTS Temperature/Weather Playground # of Children Time of day
