Pg. 211: 3,8,13,14,15,19

Lesson 16 - 5.4 #3 Graph on same graph: .

Lesson 16 - 5.4 #8 Match the graph of the functions with transformation: (i) y = f(2x) (ii) y = 2f(2x) (iii) y = f( ½ x).

Transformation Graph
(i) e
(ii) i
(iii) No match

Lesson 16 - 5.4 #13 Graph transformation of graph (horizontal stress / compression):

Lesson 16 - 5.4 #14 For the function f(x) in #13, write a formula in terms of f(x) for the transformation shown below: .

Lesson 16 - 5.4 #15 Graph transformation of graph (horizontal stress / compression):

Of unusual function:

(a) y = f(3x) Note: Compress hoz. by 1/3

(b) y = f(-2x) Note: Flip y-axis and compress hoz. by ½ .

(c) y = f ( ½ x) Note Expand hoz. by 2

Lesson 16 - 5.4 #19 State which trans. represents which graph:

(a) f(x) (b) f(-2x) (c) f(- ½ x) (d) f(2x)
