HW: Complete desmos: practice with inverse functions. Turn in any missing work. Retake on test #1 is due by 2/19.
We completed the last page of our notes on inverse functions. Then students worked on a desmos activity: practice with inverse functions. We did the first 6 slides together. Students are to complete the rest of the activity.

Students looked at composite functions graphically, and looked at the types of functions that when composed created the line y = x. We saw that the inverse switches (reverses) the order of the coordinates in the original function. We also could see that the inverse function undoes the original function. We used this idea to create the inverse function. Then we looked at these graphically using desmos. We saw that the function and its inverse are reflections over the line y= x. We also showed how to find a function's inverse algebraically by using the switch and solve method.

Students completed a 5 question review of function operations & compositions. We checked this together and then students completed WS 6-6 Test Prep 1- 5 which we also checked. On the front side of it, we discussed questions from this weekend's homework. This was collected. Students used the last part of class to complete their partner quiz on function operations & composition.
HW: Complete any missing work! Students completed a 10 question warm-up working with a partner, answers were posted on the board. We discussed these and then played an 8 question Kahoot game that composed functions. Lastly, students were together on a partner quiz that will be completed on Monday, February 11th.
HW: Complete Function Composition Worksheet (1 - 20) and any missing work. We checked over WS 6-6 and it was collected. Students had time to work on WS Function Operations & Composition. We discussed #30 and #31 together. We showed how we could check our answer graphically with desmos.
HW: Complete WS Function Operations & Composition. Retakes for test #1 must be done by 2/19. We completed our last page of notes on applications of composite functions. Then we went over WS 6.6 Reteaching. Next we played a Kahoot game that reviewed composite functions algebraically, graphically, and with tables.
HW: Complete WS 6.6 (do both sides). Students were reminded of retake opportunity for test 1 and this must be completed by February 19th. All missing work must be completed prior to meeting with me.
We completed our notes on combining functions using operations addition, subtraction, multiplication, and division. We also showed how to compose functions.

Retakes must be completed by 2/19.
Students turned in missing work and checked their study guide with the answer key on google classroom. We also went over questions from the review for their first test of the semester. Students also solved 3 radical equations. We reviewed the graphing method with the TI-Nspire calculators.
HW: Complete any missing work, including DE Quizzes. Your first test is Monday, February 4th. Enjoy the warmth this weekend! |
