You need to assign a function f(x) = y that helps you to find given ordered pairs, hence, you need to find a rule that holds for all the given pairs, such that:

f(x) = 4x - 2

You need to test if the equation of the function holds for all the given pairs, hence, you need to replace the values of `x = {1,3,5,7}` and you need to get the corresponding values `y = {2,10,18,26}` , such that:

`x = 1 => f(1) = 4*1 - 2 = 2` valid

`x = 3 => f(3) = 4*3 - 2 = 12 - 2 = 10` valid

`x = 5 => f(5) = 4*5 - 2 = 20-2 = 18` valid

`x = 7 => f(7) = 4*7 - 2 = 28 - 2 = 26` valid

Hence, the ordered pairs have been generated using the function `f(x) = 4x - 2.`
