I'm assuming that you want one or more examples of an ordered pair for the function y = f(2x).
But perhaps you meant to ask how the graphs of f(x) and of f(2x) would be different.
That "2" in f(2x) has the effect of compressing (shortening) the output of the function; the resulting graph would take up just half as much horiz. space as would that of f(x).
If the function were f(x) = x^2, then f(1) would be 1^2 = 1, and the resulting ordered pair would be (1,1).
f(2x) would be (2x)^2, or 4x^2, so that f(2*1) would be 4(1)^2, or 4. An ordered pair would then be (1,4).
