Stepbystep explanation:
first of all, it is important to remember that f(x) stands for y, it calculates the y coordinate for a given x coordinate.
so, now, by comparing the two points
(1, 1)
(2, 7)
what do we need to do to f(x) just in the "outside" (without knowing the inner details of f(x)) to create (2, 7) ?
the first thing we see : the negative y (7).
so, the first transformation is : f(x)
that would move the point to (1, 1)
because the same point is now suddenly at x=2 (instead of 1), what do we need to do to the argument of 2 to bring it back to the original 1 (so that the original function can be performed on the original x=1) ? we need to subtract 1.
so, after the second transformation we have : f(x1)
that would move the point now to (2, 1)
so, the only thing missing is to bring y from 1 to 7. we need to subtract 6 from the original result.
so, after the third transformation we have : f(x1)  6
and that finally moves the original point to (2, 7)
