Question

Jika diketahui sebuah fungsi f(x)=×pangkat2+3 dengan daerah asal = {4 bilangan prima pertama},maka tentukan ragennya

Answer 1

F(x) = x^2 + 3
domain = {2, 3, 5, 7}

f(2) = 2^2 + 3
f(2) = 4 + 3
f(2) = 7

f(3) = 3^2 + 3
f(3) = 9 + 3
f(3) = 12

f(5) = 5^2 + 3
f(5) = 25 + 3
f(5) = 28

f(7) = 7^2 + 3
f(7) = 49 + 3
f(7) = 52

range = {7, 12, 28, 52}

semoga benar yaa... ;-)
