Answer: B
Step-by-step explanation:
To find (f-g)(x), you simply subtract f(x) and g(x). With the given functions of f(x) and g(x), we can directly subtract them.
f(x)-g(x) [plug in f(x) and g(x)]
-3x+2-x³ [rewrite in the correct order]
-x³-3x+2
Since there are no like terms for us to combine, B is our correct answer.
