Weds. March 10, Last Day of Unit 5

Today, we began class by finding the equations for two mystery graphs. The first one had the equation which caused the graph to look like this:

The second graph's equation was which caused the second graph to look like this:

After discovering the equations for the two mystery graphs; we turned our attention to number 21 and 22 of Francois and his Pedometer. For number one we noted that =. After evaluating number twenty two we discovered that his set for all distances was 2.42 + 2k where k is an integer but also at 3.86 + 2k where k is also an integer.

Following the warm-up, our class reviewed Quiz 4 of Unit 5. The two numbers that we paid special attention to were number 1 and 4. For number 1, we noted that if you take and you added you would get , but if you added another you would end up with . This means, that all you have to do next is find the sin() which is . For number 4, one thing to keep in mind is that in functions, there is an opposite order of operations. This means that the easiest way to solve the problem is by finding your a, b, and c value then plugging them into a equation which looks like this: , the next step is to distribute your which makes a=2, b= and c=-.

Once we finished going over the Unit 5 Quiz 4 and any questions students had trouble on, we took the review quiz. The quiz will only count towards your quarter grade if you want it to. The quiz questions were the exact same as the ones on the previous quizzes. Next class, there will be the unit test covering chapter four. Mr. O'Brien suggested to students that they should challenge themselves while studying for the test by working on more complex and conceptual questions than the basic review.

The next class Scribe will be Tyler.
