Question

Suatu fungsi dinyatakan dengan F(x)=2x dengan daerah asal (-3,-2,-1,0,1,2)


tentukan daerah hasil fungsi tersebut

Answer 1

Ganti x menjadi daerah asal
f(-3) = 2 x -3
       = -6
f(-2) = 2 x -2
       = -4
f(-1) = 2 x -1
       = -2
f(0) = 0
f(1) = 2 x 1
       = 2
f(2) =  2 x 2
       = 4

Answer 2

F(x) = 2x
jawab :
f(-3) = 2 (-3) = -6
f(-2) = 2 (-2) = -4
f(-1) = 2 (-1) = -2
f(0) = 2 (0) = 0
f(1) = 2 (1) = 2
f(2) = 2 (2) = 4
