a. {2,4,6,8,10}; The abscissa is half the ordinate.
answer: (2,4),(4,8),(6,12),(8,16),(10,20)
b. {0,1,2,3,..., 9}; An abscissa is a natural number, and ordinate is a prime number.
Answer:
(1,1),(1,2),(1,3),(1,5),(1,7)
(2,1),(2,2),(2,3),(2,5),(2,7)
(3,1),(3,2),(3,3),(3,5),(3,7)
(4,1),(4,2),(4,3),(4,5),(4,7)
(5,1),(5,2),(5,3),(5,5),(5,7)
(6,1),(6,2),(6,3),(6,5),(6,7)
(7,1),(7,2),(7,3),(7,5),(7,7)
(8,1),(8,2),(8,3),(8,5),(8,7)
(9,1),(9,2),(9,3),(9,5),(9,7)
c. {-2-1,0,1,2}; y =3-x/2
(-2,4),(-1,7/2),(0,3),(1,5/2),(2,2)
2. Determine the domain and the range of the relation in item no. 1.
domain: {2,4,6,8,10}
range: {4,8,12,16,20 }
