### Robert's Scribe

Robert is having computer problems. He emailed me his "scribe" report. Here it is:

Hello people this is Robert. Well we started off the class by doing two review questions on finding the roots. These were the examples given:

^ ----> means "to the power of"

f(x) = x^2 + 2x - 4 f(x) = x^2 + 2x + 1 - 1 - 4 y = (x + 1)^2 - 5 0 = (x + 1)^2 - 5 5 = (x + 1)^2 +/- sqr root of 5 = x + 1 -1 +/- sqr root of 5 = x | f(x) = -x^2 + 4 x - 7 y = -(x^2 - 4x + 4 - 4) - 7 y = -[(x - 2)^2 - 4] - 7 y = -(x - 2)^2 + 4 - 7 y = -(x - 2)^2 - 3 0 = -(x - 2)^2 - 3 No Roots |

Then after those question we then did two problems in class. The first type of problem dealt with a farmer or someone that needed to make a rectangular area with a certain amount of fencing using one side of something like a barn for example. We then had to find the dimensions that would yield the maximum area. One thing that Mr. Kuropatwa really made clear was that when finding the answer in these problems always write the original equation. For example Area = ( Length ) ( width ). The second problem had us use a equation to find the vertex and x-intercepts.

Following all of the questions and problems Mr. Kuropatwa gave us a review and told us that if we did the review and got it all right we would ace the test. Finally he told us that tomorrow we would have a pre-test followed by a test the next day. Tomorrows scribe is...Craig K.

Good Job Robert. You gave us an excellent understanding of the root's thing that we learned. Good example.
