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

Week Three
Most composite figures (except of a circle, ellipse, etc.) can be decomposed into
triangles.
Connect opposite vertices
Draw the heights for each triangle. The heights must be perpendicular to the
base.
Measure the bases and the heights and fi

Week Six
Quadratic Functions
Highest exponent is 2
Minimum and/or Maximum value
Finding the equation of a quadratic line
Vertex form with a vertex of (0,2):
To find a plug in a point for f(x) and x. Then solve for a

Week One
Best Fit Lines
Describing Motion
Motion can be described by finding function that shows objects position, velocity,
or acceleration.
The most standard representation is a position function that can be used to find
object location at any time in

Week Five
Piece-wise function
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.
Example:
Rules
Th

Week Four
System of linear equations is defined as a collection (set) of linear functions with
common variables.
Graphical Method of Solving
Solve each equation for y
Graph the equations
Find intersection
Algebraic Method of Solving
Elimination Method

NOTES
Howdy,
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
