Today at about 12pm, i went in to Mr. Jacksons room to do some homework, as questions, and catch up on the past 2 days that i've missed. Walking into his room, i knew i had a alot of questions but they were accompanied by no answers. I was very happy that some of my class members and I got the chance to come in and have a Precalc Functions get togther with Mr. Jackson.
I learned several things today. Like when writing a quadratic equation, and you are given the x intercepts and a low or high point, it is much easier to sketch out the picture so you hae find the middle of the x intercepts. Finding the middle gets you the x part in the coordinates for the vertex. And the y part of the coordiante is whatever number you are given for your low or high point. After that, then you plug the vertex in the quadratic formula, which is y=a(x-h)*squared* + k. When the vertex is plugged in, then you pick one of the x intercepts and enter it for the y and the x in the equation. I also learned that using the formual -b/2a is used alot when solving problems. Includong steps in finding tha maximum area or minimum.
The 2 hours i spent with Mr. Jackson solving and doing multiple precalc problems was definatley worth it on a beautiful sunday afternoon. I got all caught up on my homework, learned how to solve problems i didnt know how, and well i even got to have pizza and pop. All thanks to Jackson, i am now a little bit smarter then i was this morning with Precalc Functions. Thank Mr. Jackson for taking the time to teach me as weell as others today, and thank you for buying us pizza and pop. Your time and effort spent with us is appreciated greatly. Have a nice sunday Jackson, you deserve it.! ツ
