Coefficient of Determination (r2) CAN BE CALCULATED IN A TI84 CALCULATOR
Describes the percent of data variation that can be explained by derived
If r2= 0.6 then 60% of data is supported by the model.
Can take values between

Composed of different pieces or forms: quadratic, linear, cubic, etc.
Forms are restricted to specific domains x-intervals.
Can be continuous or discontinuous.
Can be increasing, decreasing, or constant.
System of linear equations is defined as a collection (set) of linear functions with
Graphical Method of Solving
Solve each equation for y

Here are general tips how to prepare for the midterm exam.
Focus on reviewing notes and labs conducted during this course. I will make the notes
from previous weeks available on eCampus. Most of the questions will ask to buil
