JAWAB :
•Domain =
{ -2 < x < 4 }
maka x = { -1,0,1,2,3 }
•kodomain =
jika rumus : f(x) = 3x - 2
maka :
f(-1) = 3(-1) - 2
f(-1) = -3 - 2
f(-1) = -5
f(0) = 3(0) - 2
f(0) = 0 - 2
f(0) = -2
f(1) = 3(1) - 2
f(1) = 3 -2
f(1) = 1
f(2) = 3(2) -2
f(2) = 6 - 2
f(2) = 4
f(3) = 3(3) - 2
f(3) = 9 - 2
f(3) = 7
•Range =
rumus Range adalah (x,y)
maka
{ (-1,-5) ; (0,-2) ; (1,1) ; (2,4) ; (3,7) }
