4.1.3. Determine whether a linear function is increasing, decreasing, or constant.
4.1.4. Solve applied problems that involve linear functions.
4.3.1. Graph quadratic functions by writing them in standard form and then using transformations.
4.3.2. Use the vertex formula to find the vertex and equation of the axis of symmetry for a quadratic function.
4.3.3. Graph a quadratic function by finding algebraically the vertex and intercepts and using them to construct the graph.
4.3.4. Use the vertex formula to find algebraically the maximum (or minimum) value of a quadratic function.

1. Learn the material in 4.1 by using "E-text, Videos, Practice" (study the text, view videos, do example problems and practice problems) AND/OR using the "Lecture Notes" (read the lecture notes, work out the examples, and check your answers using the key). Both are accessed through the MyMathLab (MML) menu on the left of this page.

2. Complete the homework assignment for 4.1. Homework assignments are accessed through "Homework" on MML menu on the left.

3. Learn the material in 4.3 by using "E-text, Videos, Practice" (study the text, view videos, do example problems and practice problems) AND/OR using the "Lecture Notes" (read the lecture notes, work out the examples, and check your answers using the key). Both are accessed through the MyMathLab (MML) menu on the left of this page.

4. Complete the homework assignment for 4.3. Homework assignments are accessed through "Homework" on MML menu on the left.

5. Learn the material in 4.5 by using "E-text, Videos, Practice" (study the text, view videos, do example problems and practice problems) AND/OR using the "Lecture Notes" (read the lecture notes, work out the examples, and check your answers using the key).

8. Complete and submit Test 2 Review (due on Wednesday, March 11). Test Reviews are accessed through "Quizzes/Test Rev" in the MML menu on the left.

9. Optional, but highly recommended: (Note: Since this is an optional activity, there is no rush to complete it by the due date for this Lesson. I recommend that you work on it during the testing window, planning to complete it before you take the test.) In addition to the Test 2 Review in MML, you will find an Optional Chapter 3 Review and an Optional Chapter 4 Review posted under "Optional Chap. Revs." in the MML menu on the left of this page. Also, you will find the key to a version of Test 2 that was given last semester posted under "Test Keys" in the MML menu on the left of this page. I highly recommend that you download, print out and work through these reviews and the old test. Complete them under testing conditions; that is, with closed book, showing all steps and in a two-hour time frame. Use the key to grade your work, and then go back and redo any problems that you missed. This activity will be very helpful in studying for the test. Remember that studying under conditions similar to testing conditions (closed book, showing all work and time restrictions) helps you to perform better on the test.

c. Test 2 Information

Test 2 will be given at the Academic Proctoring Center (APC) at both the Oceanside and San Elijo campuses. you must schedule an apointment to take your test! Call the APC at 760.757.2121 extension 6471 (Oceanside), 760.944.4449 extension 7752, or schedule an appointment online.
There is a grace period for the test that extends from Friday, March 13 through Tuesday, March 24. The campus will be closed for spring break Monday, March 16 through Saturday, March 21. You must contact me and get approval to take the test during the grace period. This semester, each student may request approval to take ONE test during the grace period for that test. Tests taken during the grace period will earn a maximum score of 70%. Students who have not taken the test by the end of the grace period will earn a zero on the test and may be dropped from the class.
