Question

Diketahui fungsi f : x ---> 1/2 x + 6. Bila domain fungsi {0, 2, 4, 6}. Maka range fungsi adalah
a. {6, 8, 10, 12}
b. {0, 6, 8, 10, 12}
c. {0, 6, 7, 8, 9}
d. {6, 7, 8, 9}

Answer 1

F(x) = 1/2 x + 6
f(0) = 1/2 (0) + 6 = 6
f(2) = (1/2)(2) + 6 = 7
f(4) = (1/2)(4) + 6 = 8
f(6) = (1/2)(6) + 6 = 9
jawaban: D
