Question

X= {-1, 0, 1, 2}

1) Y= X-2


2) Y= -2X+1


3) Y= -7+3


4)Y= -3X+4


5)Y= 2X+1

Answer 1

1-Y = X-2
Y = (-1)-2 = -3 
Y = 0-2 = -2
Y = 1-2 = -1
Y = 2-2 = 0

2- Y = -2x+1
Y= -2.(-1)+1 = 2+1 = 3 
Y= -2.(0)+1 = -2+1 = -1
Y= -2.(1)+1 = -2+1 = -1
Y= -2.(2)+1 = -4+1 = -3

3- Y= -7+3 = -4

4- Y= -3X+4
Y= -3.(-1)+4 = 3+4 = 7
Y= -3.(0)+4 = -3+4 = 1
Y= -3.(1)+4 = -3+4 = 1
Y= -3.(2)+4 = -6+4 = -2

5- Y= 2X+1
Y= 2.(-1)+1 = -2+1 = -1
Y= 2.(0)+1 = 0+1 = 1
Y= 2.(1)+1 = 2+1 = 3
Y= 2.(2)+1 = 4+1 = 5
