## MCF3M – Sept 17, 2014

I began the class today by reviewing some of the concepts we did in yesterday’s lesson.  I went over the lesson on the digital projector with the students so the students could remember what we did.  After reviewing yesterday’s lesson, I then went over the answers to the worksheet titled “1.4 Exploring Transformations of Quadratic Functions Worksheet” with the students on the digital projector.  I also showed the students the link I had given them in yesterday’s blog (see Sept 16 blog posting) to complete the worksheet.  After going over the answers, I then started the lesson for today which was a continuation of the lesson we did yesterday titled “1.5 Graphing Quadratic Functions by Using Transformations”.  Yesterday we looked at “h” and “k” and how they affect the quadratic function y=x^2.  Today we looked at how the “a” value affects y=x^2.  I then showed the students 2 different methods for graphing a quadratic function in vertex form   y = a(x-h)^2 + k (using “h”, “k” and “a”).  The second method I taught the students is a new method which they told me they haven’t done before.  This method is called “The Step Method”.  I then assigned the homework for the students to work on for the remainder of the period (Page 47 – 49 # 1 & 7).

Below you will find a copies of the handouts/worksheets that were distributed/assigned in today’s class.

Sept 17 – Lesson – 1.5 Graphing Quadratic Functions by Using Transformations (continued)

Graph the Transformations (extra examples) (I didn’t show this in class, but this is an extra example for the “Step Pattern” method)

Describe the Transformations (extra examples) (I didn’t show this is class, but this is an extra example for describing transformations)
