Today in class we really worked towards formalizing the differences between horizontal (stretch/shrink) and vertical (stretch/shrink). Please be sure to keep those things straight as you complete the PROBLEM SET for homework on Monday.

Today in class we (finally) got to start our study of Horizontal Stretch/Shrink.

Please come to class on Monday with Examples 1 and 2 complete. Be sure to carefully look at which x-values have the same y-values!

Today in class we focused on Horizontal Transformations of functions.

Pleases complete the Problem Set tonight for homework.

Today we formalized how changing f(x) will transform a function.

Right now we can vertically translate, reflect, and vertically stretch (and shrink) a function.

Tomorrow we will add horizontal transformations.

Don’t forget to complete the Problem Set tonight for homework.

Tonight, please complete Exploration Challenge #1.

If you have any questions about notation or wording, please post them on the blog.

Today in class we corrected our homework. Then we spent the rest of class practicing how to use graphs to help us solve complex equations.

Tonight, please complete the ENTIRE problem set. Be sure to spend extra attention on problem 6. How can you check to make sure that you piecewise function matches the given graph?

Sometimes equations are Way Too Complicated to solve algebraically. Even when it is possible, it requires an enormous amount of steps, opening up more opportunities to make mistakes.

That is why we sometimes use graphs to solve equations.

Over the weekend, please complete Exercises 1 – 5.

Today in class we focused on how to read piecewise functions, graph piecewise functions, and use open and closed circles (like in number lines) to describe the domain of a function.

Please complete Problems 6 and 7 through C tonight for homework on page S98.

Tonight for homework:

1. Create an absolute value function to match the graph below. Then create 2 linear functions (restricted with a domain) to match the absolute value function.

2. Create the equation for an absolute value function with an global minimum at (1, -2) and a y – intercept of (0, -1)

3. Challenge Problem: Can you create the equation for an absolute value function with an global minimum at (1, -2) and a y-intercept of (0,0)? Is that enough information? If so, create an equation. Otherwise, describe what additional information is necessary.
