4-101. ​ Throughout this book, key problems have been selected as “checkpoints.” Each checkpoint problem is marked with an icon like the one at left. These checkpoint problems are provided so that you can check to be sure you are building the skills from this course at the expected level. If you have trouble with checkpoint problems, refer to the review materials and practice problems that are available in the Checkpoint Materials at cpm.org.

This problem is a checkpoint for graphing transformations of functions. Given the graph of $y=k(x)$ at right, sketch the following transformations.

1. $y=k(x-2)+3$

2. $y=k(-x)-2$

3. $y=\frac{1}{2}k(x)+1$

Ideally at this point you are comfortable working with these types of problems and can complete them correctly. If you feel that you need more confidence when completing these types of problems, then review the Transformations of Functions Checkpoint materials and try the practice problems provided. From this point on, you will be expected to do problems like these correctly and with confidence.

Answers and extra practice for the Checkpoint problems are located in the Reference Tab of your eBook.
