B’=?
Question 9 options:

a) (3, 2)

b) (-4, 1)

c) (4, 0)

d) (4, 1)

Answer 1

use formula
p(x,y)= Q ( x, 2k-y) for y=k

Answer 2

i dont understand

Answer 3

\[p(x,y) \rightarrow p^l ( x^ly^l) \]

Answer 4

\[x^l= x \]

Answer 5

\[y^l= 2k-y\]

Answer 6

and for this question k=1=y

Answer 7

so the answer is \[x^l= 4 \]

Answer 8

so c?

Answer 9

\[y^l= 2\times 1 - 2 \]

Answer 10

yah ! it is c

Answer 11

ok thanks :DD
