f(0) = √(0(6-0) = 0
f(0,5) = √(0,5(6-0,5) = √(0,5(5,5) = √2,75 ≅ 1,658
f(1) = √(1(6-1)) = √5 ≅ 2,236
f(1,5) = √(1,5(6-1,5)) = √(1,5(4,5)) = √6,75 ≅ 2,598
f(2) = √(2(6-2)) = √(2(4)) = √8 ≅ 2,828
f(2,5) = √(2,5(6-2,5)) = √(2,5(3,5)) = √8,75 ≅ 2,958
f(3) = √(3(6-3)) = √(3(3) = √9 = 3
f(3,5) = √(3,5(6-3,5)) = √(3,5(2,5)) = √8,75 ≅ 2,958
f(4) = √(4(6-4)) = √(4(2) = √8 ≅ 2,828
f(4,5) = √(4,5(6-4,5)) = √(4,5(1,5)) = √6,75 ≅ 2,598
f(5) = √(5(6-5)) = √(5(1)) = √5 ≅ 2,236
f(5,5) = √(5,5(6-5,5)) = √(5,5(0,5)) = √2,75 ≅ 1,658
f(6) = √(6(6-6)) = √(6(0)) = 0
2) f(0,2) = √(0,2(6-0,2)) = √(0,2(5,8) = √1,16 ≅ 1,08
