1st, 2nd, 3rd Hours:
Bellwork reviewed graphing quadratic equations and using a quadratic model of a situation to find the maximum or minimum of the function and when it occurs.
The remainder of the period we began our discussing on Sec 5-3, Vertex Form for the equation of a quadratic function.
Hwk #16 is due tomorrow. Sec 5-2
Students are to use the practice sheet I gave them.

4th & 5th Hours:
Bellwork reviewed the steps used to make a scatter plot using the graphing calculator and finding the regression equation to model the data (Sec 2-4). Students were given a sheet of instructions to help them through this process.
The remainder of the period we continued discussing scatter plots and the equations that model them, including performing a Quadratic Regression in the event the scatter plot looks like a curve instead of a line. We also began discussing what the correlation coefficient(r) tells us.
Hwk #13 is due tomorrow. Sec 2-4.
Students were given a Practice Sheet for this homework.
