Today’s Objective: Finish Horizontal Translation
Materials: Calculator, Springboard, & P3
In Items 1 and 2, each graph shows a vertical translation of the graph of f(x) = x. Write an equation to describe the graph. 

2. Bell Work Tuesday 11/4/14 Today’s Objective: Scatter Plots
Materials: Calculator, Springboard, & P3
An air conditioner unit costs $450 plus $40 per month to operate.
Write a function that describes the total cost of buying and operating the air conditioner for x months.
Use your calculator to graph the function.
What is the y-intercept? What does it represent?
How would the function change if the price of the air conditioner went on sale to $425? How would the graph change?

3. Bell Work Wednesday 11/5/14 Today’s Objective: Linear Regression
Materials: Calculator, Springboard, & P3
In Items 1 – 4, identify the transformation of f(x) = 2x to the graph of g(x).
g(x) = 2x – 3
g(x) = 2(x – 3)
g(x) = 2x + 4
g(x) = 2(x + 4)

4. Bell Work Thursday 11/6/14 Today’s Objective: Linear Regression
Materials: Calculator, Springboard, & P3
The graph of which function is a translation of the graph of f(x) = x2 five units to the right?
g(x) = x2 – 5
g(x) = (x + 5)2
g(x) = (x – 5)2
g(x) = x2 + 5
