Question

F(x)→-2x + 1
Daerah asal = {-3,-2,-1,0,1,2,3}
Tolong dibantu yaa

Answer 1

Daerah hasil
f(-3) = -2(-3) + 1
       = 6 + 1
       = 7
f(-2) = -2(-2)+1
       = 4 + 1
       = 5
f(-1) = -2(-1) +1
       = 2 + 1
       = 3
f(0) = -2(0) +1
     = 0+1
     = 1
f(1)  = -2(1)+1
       = -2 + 1
       = -1
f(2) = -2(2)+1
      = -4+1
      = -3
f(3) = -2(3)+1
     = -6+1
     = -5

Answer 2

F(x)---> -2x + 1
. -2x(-3) + 1
= 6 + 1
= 7
= ( -3, 7)
. -2(-2) + 1
= 4 + 1
= 5
= (-2, 5)
. -2(-1) + 1
= 2 + 1
= 3
= (-1, 3)
. -2(0) + 1
= -0 + 1
= -1
= ( 0, -1)
. -2(1) + 1
= -2 + 1
= -1
= (1, -1)
. -2(2) + 1
= -4 + 1
= -3
= (2, -3)
. -2(3) + 1
= -6 + 1
= -5
= (3, -5)
jadi range atau nilai hasilnya adalah = ( 7, 5, 3, -1, -3, -5)
