Homework: HW03 Plotting and Graphing (Make sure your x-axis counts by 0.5, and your y-axis counts by 1, just like in the picture). Plug in x values to get the output f(x) values. Then plot the points, and connect the points to sketch the graph. (blank graph sheet to print)
8/20/24 – Local Min/Max, Intercepts, and Algebra
Summary: Today we looked at graphs and identified local minimum(s), local maximum(s), x-intercept(s), and y-intercept(s). See homework #2 below…
Homework: HW02
8/19/24 – Plotting Points and Other Basics
Summary: Today we practiced plotting points and other basics. See today’s activity below…
We also entered out test corrections into the computer.
Homework: Today’s activity slides #1-9 (CA05)
8/16/24 – Intervals and End Behaviors Test
Summary: Today we took our first test on intervals, end behaviors, inequality notation, number lines, and more. Please use the links below to start you test…
Homework: Look at the questions you missed and do test corrections on paper.

8/12/24 – Graph Characteristics Practice
Summary: Today we practiced labeling our intervals of graph characteristics.
Homework: HW01
8/9/24 – Introduction to Graph Characteristics
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
8/8/24 – More Intervals
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)
