diketahui f:x--->3-2x.jika domain f adalah D={x|_

Jawab :

Domain = { 0 , 1 , 2 , 3 , 4 }

Ditanya Range ?

a) X = 0
f(x) = 3 - 2x
f(0) = 3(0)-2
= 0 - 2
= -2

b) X = 1
f(x) = 3 - 2x
f(1) = 3(1) - 2
= 3 - 2
= 1

c) X = 2 
f(x) = 3 - 2x
f(2) = 3(2) - 2
= 6 - 2
= 4

d) X = 3
f(x) = 3 -2x 
f(3) = 3(3) - 2
= 9 - 2
= 7

e) X = 4
f(x) = 3 - 2x
f(4) = 3(4) - 2
= 12 - 2
= 10

Jadi Rangenya = { -2 , 1, 4 , 7 , 10 }
