range dari fungsi f:x ke 3x+8 dengan domain {-2,-1,0,1,2} adalah

F(x) = 3x + 8

1. F(-2) = (3 × (-2) ) + 8
F(-2) = -6 + 8
F(-2) = 2

2. F(-1) = (3 × (-1) ) + 8
F(-1) = -3 + 8
F(-1) = 5

3. F(0) = ( 3 × 0 ) + 8
F(0) = 0 + 8
F(0) = 8

4. F(1) = (3 × 1 ) +8
F(1) = 3 + 8
F(1) = 11

5. F(2) = (3 ×2) + 8
F(2) = 6 + 8
F(2) = 14

Domain : { -2, -1, 0 , 1 , 2 }
Range : { 2, 5, 8, 11, 14 }
