Comparing the functions, from the tables, it is found that (f - g)(x) is positive in the interval (–∞, 9) .
----------------------
- For the subtraction function, we simply subtract both functions, thus:
[tex](f - g)(x) = f(x) - g(x)[/tex]
- It is positive if f is greater than g, that is: f(x) > g(x).
- It is a linear function, so one function is greater before the equality, one after.
- They are equal at x = 9.
- If x < 9, f(x) > g(x), and thus, (f - g)(x) is positive, which means that the desired interval is:
(–∞, 9)
