diketahui A={1,2,3,4} dan B={1,2,3,4,5,6,7,8} Suatu fungsi f:A ke B ditentukan oleh f(x)=2x-1 tentukan range nya

f: A → B
A = domain (x)
B = kodomain (y)
f(x) = 2x - 1

A = {1, 2, 3, 4}
f(1) = 2(1) - 1 = 2 - 1 = 1
f(2) = 2(2) - 1 = 4 - 1 = 3
f(3) = 2(3) - 1 = 6 - 1 = 5
f(4) = 2(4) - 1 = 8 - 1 = 7

Range = {1, 3, 5, 7}
