### Transcript of "Compositions"

1. 1. Aim: How do we find compositions of functions? MB43 2/27/09 Lomas Do Now: Dialate Δ ABC by D 2 f(x)=2x g(x)=x-3 Find f g(4) 1) 2) HW Review: 8,16,27 3) Find r y-axis D 3 (4,-2) A B C HW: Read 584-588 Do 588-9 #2-4
2. 2. Aim: How do we find compositions of functions? MB43 2/27/09 Lomas Find r x-axis T 3,-2 (ΔABC) HW: Read 584-588 Do 588-9 #2-4 A B C
3. 3. Aim: How do we find compositions of functions? MB43 2/27/09 Lomas The coordinates of the vertices of ΔABC are A(1,3), B(1,6), and C(3,3). a. Find the coordinates of the vertices of ΔA'B'C', the image of ΔABC under a point reflection in the origin. b. Find the coordinates of ΔA&quot;B&quot;C&quot;, the image of ΔA'B'C' after a reflection in the y-axis. c. On graph paper, draw and label ΔABC, ΔA'B'C', ΔA&quot;B&quot;C&quot;. d. Name the single transformation that maps ΔABC onto ΔA&quot;B&quot;C&quot; Group project: HW: Read 584-588 Do 588-9 #2-4
