HW: Complete both sides of Test Prep 6-8 & complete Desmos: transformed square root functions. Test will be next week on 3/6.
Students completed Test Prep 6-8 in class and we went over it. Students also played a 5 question Kahoot game on graphing radical functions. Students used the last 15 - 20 minutes to complete quiz 6.

We completed the packet from yesterday, going over how to rewrite radical equation so that the a, h, and k can be correctly identified. Students turned this in with WS Graphing Cube Root Functions. Students also had time to work on Desmos: Transformed Square Root Functions.
HW: Complete Desmos: Transformed Square Root Functions (code is in your google classroom). Quiz tomorrow, February 28th, on graphing radical functions. Test next week, most likely Wednesday, 3/6. Students completed a 3 question warm-up on graphing radical functions. These were checked in class. Then we complete problems 1, 3, & 6 together. We showed how to rewrite a square root function so that the a, h, and k are properly identified.
HW: Complete 1 - 12 on Graphing Radical Functions WS 2. We completed our notes on graphing cube root functions. We also completed the last 6 graphs on the back page which reviewed both square root and cube root functions. A key difference between these graphs is that the domain and range of the cube root function is all real numbers. We showed that the pivot point (or center point) of the cube root function is (h, k). On the square root function, the point of origin is (h, k).

We checked the WS 6.8 Reteaching graphs and did about 4 together. This was collected. We worked through about the first 10 slides on the Desmos assignment investigation square root graphs. Students had the rest of class to complete it. They were also given a second desmos activity on transforming the square root function that used marbleslides!
HW: Complete the 2 Desmos activities (codes are in your google classroom) We completed the first page of our 6.8 notes on graphing the square root function. We reviewed what we learned about transformations and the effects of a, h, and k. We saw that the domain and range are connected to h and k.

They also had time to complete the WS Kuta Inverse Functions as well as the WS Inverses of Functions/More Domain & Range (1 - 20).
Students complete Quiz #5 during the last 20 minutes of class. HW: Complete WS Inverses of Functions/More Domain & Range (1 - 20). We went over Test Prep 6-7 and then students had time to work on WS Kuta Inverse Functions. We did 17 & 18 together. Students also received their Friday quizzes back.
HW: Complete WS Kuta Inverse Functions (skip 7 & 8), work on DE Quiz Inverses. Quiz on Inverse Functions is tomorrow, 2/20. Students completed a warm-up question using desmos to find the inverse of y = 2x - 8. We checked the inverse graphically by testing 2 points, composing the functions to see that the composition give us the line y = x. We also checked this algebraically by composing the functions. Then we looked at how we could use the vertical line test (VLT) to see if a graph is a function (must have only 1 intersection point at a time). We saw that both the line y = 2x - 8 and its inverse are functions.
We also looked at the inverse of y = x^2. We saw that we needed to use both positive and negative square root of x to generate the inverse graph. Our original function passed the VLT; however, its inverse did not. We discussed how the horizontal line test (HLT) will tell if the original function's inverse is a function. Students complete 18 question statement sheet about inverses, which we checked in class. Lastly, student used the last 15 - 20 minutes to complete quiz #5. HW: Complete Test Prep 6-7 (on the back of the 18 Quick Questions - Inverse Function sheet). We went over WS Inverse Functions - Equations. Then we did the first 2 questions on the back side (identifying pairs) together. Students had time to complete the other 6 questions and also complete the desmos activity: practice with inverses.
HW: Turn in any missing work and complete the desmos activity: practice with inverses. Quiz #5 on functions operations & composition is tomorrow. Use your partner quiz from last week for review. |
