Answer:
f(x) = x-1
Explanation:
You want a function f(x) such that f(7) = 6.
Function
As you know, there are infinitely many possibilities. The simplest is ...
f(x) = 6
A linear function that goes through the point (x, y) = (7, 6) can have any slope m. Such a function can be written in the form ...
f(x) = m(x -7) +6
If the slope is 1, then this becomes ...
f(x) = x -1
Any parent function that includes the point (0, 0) can be translated to the point (7, 6). For example, ...
f(x) = sin(x -7) +6
