Summary: Today we practiced labeling our intervals of graph characteristics.

Homework: HW01

Summary: Today we examined four characteristics of graphs. Specifically the intervals where the graph is…

• Increasing
• Decreasing
• Positive
• Negative

In the graph below the red interval -1<x<2 represents where the graph is decreasing (down-hill). The green intervals -∞<x<-1 and 2<x<∞ represent where the graph is increasing (uphill).In the graph below the yellow intervals -2<x<0 and 3.2<x<∞ represent where the graph is positive (above ground). The purple intervals -∞<x<-2 and 0<x<3.2 represent where the graph is negative (below ground).
The examples above are all shown using inequality notation.

Homework: None  HW01

Summary: Today we continued to practice writing intervals using the five notations that we learned about yesterday. At the end of class we took a short quiz (TQ03)

Homework: none

Summary: Today we learned about five different ways to express intervals…

Intervals are ways to express a the range of numbers between two values. Above are examples of how to write the interval between two and five (including five).

Homework: none

Summary: Today we reviewed End Behaviors of graphs. These are the two “arms” of the graph.

In this graph example, the left arm goes up and the right arm goes down. We would write this as…

x→-∞ y→∞
x→∞ y→-∞

which translates to…

x→-∞ y→∞ (LEFT arm UP)
x→∞ y→-∞ (RIGHT arm DOWN)

We can use chart below to to describe the four directions; LEFT, RIGHT, DOWN, UP.

 

At the end of class we took a short quiz on End Behaviors (TQ02). Example Task (Graph Family Images Sheet).

Homework: none

Summary: Today we found patterns in counting the number of squares in a square grid.  We used these patterns to count the number of squares on a chessboard. We even looked at counting the square on a  100×100 grid.

Then we turn our attention to a set of graphs and grouped them into different families based on their characteristics (CA02).
