3. Agenda Fractions Changing Fraction-to-Decimals
Setting Windows to see Graphs
Setting Tables
STAT PLOTS
STAT EDIT STAT CALC 4/5
Systems of Equations (Matrix)
Systems of Equations (Intersect)
Attributes of Quadratics (Zeros, Min, Max)

4. Fractions and Changing Fractions-Decimals or Decimals-Fractions
Write each in decimal form
𝟏𝟐 𝟕
𝟏𝟑 𝟗
𝟒 𝟏𝟖
Write each in fraction form
8.75
4.6
3.3

5. Setting Windows
Set the Window values so you can see the graph. Remember if you are going to use 2nd Calc 2,3,4, or 5 you have to see the point on the graph

6. Setting Tables
Instead of solving with fractions we can set the table so the calculator does the work!
