Suatu fungsi g(x) =2x+3 jika domain {-1,0,1,2} maka range fungsi g(x) adalah

1. F(x) = 2x + 3
F(-1) = ( 2 × (-1) ) + 3
F(-1) = -2 + 3
F(-1) = 1

2. F(0) = (2 × 0) + 3
F(0) = 0 + 3
F(0) = 3

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

4 F(2) = ( 2 × 2 ) + 3
F(2) = 4 + 3
F(2) = 7

Domain : { -1, 0, 1, 2 }
Range : { 1, 3, 5, 7}
