Phase:
During/Explore/Explain
Activity:
This activity will be used during a lesson on graphs of functions using technology. Students will complete the activity Let's Experiment With Graphs of Functions Using Technology. Students will complete this activity individually or with a partner.
Assessment Strategies:
The activity Let's Experiment With Graphs of Functions Using Technology! can be used to access the student's ability to identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k using technology, to find the value of k given the graphs and to recognize even and odd functions from their graphs.
Advanced Preparation:
Students will need to understand the basic vocabulary of functions and graphs. The students will need to understand the basic operations of the Desmos graphing calculator. The Desmos graphing calculator can be introduced right before this activity or may have been introduced prior to this lesson. The teacher may work the first set of problems together on the projector to show the students how to use the Desmos graphing calculator. The teacher can add the activity to Google Classroom for the students to view. The teacher can copy the activity Let's Experiment With Graphs of Functions Using Technology! for the students to write on and turn in.
Variation Tips (optional):
The learning activity Let's Experiment With Graphs of Functions Using Technology! can be extended to allow the students to develop their own transformations of functions. Also, it could be used to show how that as the slope of the function gets closer to 0 from the positive direction how the graph will start to get closer to the x-axis and how that as the slope grows farther from 0 in the negative direction that the graph gets closer to the y-axis.
Notes or Recommendations (optional):
Make sure that you remind the students that as they are copying the graphs that they are careful to ensure that the individual points on the graphs in the calculator are the same as the points on their graphs.
