Tentukan daerah hasil fungsi f(x)=x²+2x+3 untuk daerah asal Df={x/ 0 ≤ x ≤ 7, x € R}

domain = {0, 1, 2, 3, 4, 5, 6, 7}

rumus fungsi :
f(x) = x^2 + 2x + 3
f(0) = 0^2 + 2(0) + 3 = 3
f(1) = 1^2 + 1(2) + 3 = 6
f(2) = 2^2 + 2(2) + 3 = 11
f(3) = 3^2 + 2(3) + 3 = 18
f(4) = 4^2 + 2(4) + 3 = 27
f(5) = 5^2 + 2(5) + 3 = 38
f(6) = 6^2 + 2(6) + 3 = 51
f(7) = 7^2 + 2(7) + 3 = 66

sehingga
range = {3, 6, 11, 18, 27, 38, 51, 66}
