jika f(x)=3-2x dengan domain x {-2,-1,0,1,2} maka rangenya adalah..

f (x) = 3-2x
f (-2) = 3- 2.-2 = 3-(-4)=7
f (-1) = 3- 2.-1 = 3-(-2) = 5
f (0) = 3 - 2.0 = 3-0 = 3
f (1) = 3 - 2.1 = 3-2 = 1
f (2) = 3 - 2.2 = 3 - 4 = -1
(disini maksudnya titik itu kali)

Jawab :

Domain : {-2 , -1 , 0 , 1 , 2 }
f(x) = 3 - 2x

f(-2) = 3(-2) - 2 = -6 - 2 = -8
f(-1) = 3(-1) - 2 = -3 - 2 = -5
f(0) = 3(0) - 2 = -2
f(1) = 3(1) - 2 = 3 - 2 = 1
f(2) = 3(2) - 2 = 6 - 2 = 4
