1. Give the coordinates of each transformation of (2, –3). 1. horizontal translation of 5 2. vertical translation of – 1 3. reflection across the x-axis 4. reflection across the y-axis (7, –3) (2, 3) (2, –4) (–2, –3) Bell Ringer number your answers; you do not need to write question

2. Transform linear functions. Solve problems involving linear transformations. 1.3 Objectives Students will: learn to transform functions by transforming each point. Transformations can function notation also be expressed by using function notation.

3. Teaching note following slide Remind students what it means to be symmetric Get students to explain difference is opposite sign; possibly label coordinates and see if they can see change of sign. ** use thin paper for demo** Fold paper along axis of symmetry  darken shape  press down, this will get them the image. Have students realize reflection simply changes sign in front of # prior to revealing property

6. k

8. h

10. m (a)

11. Teaching note Pass out packet, 4 pages, FUNCTION TRANSFORMATIONS as students are copying next slide. (assign due date) Recommend students make a flip chart Set up side work board for following slides. Students need to see addition of 5 to (1, 6). – use transparency with overhead – ** copy slide 13 & 14 onto transparency Exit Question long

12. INVESTIGATION of Function Transformations “external” changes affect the “vertical” “internal” changes affect the “horizontal”

14. WRITING TRANSFORMATIONAL CHANGES functionf(x) + 3f(x) - 25f(x)-f(x)f(x + 4)f(x - 1)f(-2x) f(x) = 4x f(x) = x 2 Describe graph changes
