If x is an even number, the function f(x) = 2x − 1 gives an odd number. identify the set of odd numbers corresponding to this set of even numbers: {0, 2, 4, 6, 8}.

X = {0, 2, 4, 6, 8}.

=> f(x) = 2x - 1

x                  f(x) = 2x - 1

0                   2*0 - 1 = - 1

2                   2*2 - 1 = 3

4                   2*4 - 1 = 7

6                   2*6 - 1 = 11

8                   2*8 - 1 = 15

{-1, 3, 7, 11, 15}
