fungsi f didefinisikan oleh f(x)=1/2x+1 dengan domain {-5,-4,-3,-2}

[tex]f(x) = \frac{1}{2} x + 1[/tex]
[tex]f( - 5) = \frac{1}{2} ( - 5) + 1 = - \frac{5}{2} + 1 = - \frac{3}{2} [/tex]
[tex]f ( - 4) = \frac{1}{2} ( - 4) + 1 = - 2 + 1 = - 1[/tex]
[tex]f( - 3) = \frac{1}{2} ( - 3) + 1 = - \frac{3}{2} + 1 = - \frac{1}{2} [/tex]
[tex]f( - 2) = \frac{1}{ 2} ( - 2) + 1 = 0[/tex]
kodomain = {-3/2, -1, -1/2, 0}
