Suatu fungsi f(x)=2x-4,dengan domain fungsi=(0,1,2,3,5,6),maka tentukan : a. Range b. Himpunan pasangan berurutan

domain ' {0,1,2,3,5,6)
0 --> 2(0) - 4 = -4
1 --> 2(1) - 4 = -2
2 -->2(2) - 4 = 0
3 --> 2(3) - 4 = 2
5 -->2(5) - 4 = 6
6 ---> 2(6) - 4 = 8

a range
{-4,-2,0,2,6,8}

b. pasangan berurut
(0,-4)
(1,-2)
(2,0)
(3,2)
(5,6)
(6,8)
