As you complete the Four Situations worksheet tonight, please take a moment to write about WHY the four equations fit each situation. Pay close attention to the STRUCTURE of the equations.

# Graphs of Functions

Tonight, please complete problems 1 – 5 on the worksheet Ten Situations.

Be sure to label your axes with specific variable names.

# 9/15 – Introduction to Functions

Be sure to come to class tomorrow with (at least) 10 quantitative variables for 3 of the situations on the Making Decisions I worksheet.

We will use these variables to build functions in class tomorrow!

# Finding Missing Sides:

# Dilations off the Grid – 9/11

Today in class we began to dilate shapes without using the coordinate plane.

Please continue to extend your study with questions 6 – 87 through 90.

# Transformations and Dilations:

Tonight please answer the following questions about translations and dilations for homework:

6 – 66, 6 – 67, 6 – 78, 6 – 80

# 9/9 – Dilations, Scale Factor, and STRETCHING

When you multiply both the x and y coordinate by the same number, that number is called a scale factor. The new image is called a dilation.

When you only multiply the x OR y coordinate by a number, then you are performing a vertical/horizontal stretch/shrink. The new shape is not a dilation, as it is not similar to the original shape.

Your homework tonight was problems 6-58 and 6-59.

# Dilations and Multiplication

You can use the following links to help you with problems 43, 46, and 47:

Please complete problems 46 – 50 (skip 47) tonight for homework!

# 09/05 – Rigid Motion (Day 3)

Today we wrapped up our work on rigid motion.

Please complete problems 6 – 26 through 6 – 28 over the weekend for homework. On Monday we will begin reviewing translations.

# 09/04 – How Can I Describe It

Tonight, please complete problems 6 – 18 through 6 – 20 for homework.

Focus on clear (precise) language to describe your transformations.
