N 2-1 < 3
n is equal to :
2-1 = 1 so n would have to be 1 in order to be less than 3
Answer:
A. H(x) is an inverse of F(x)
Step-by-step explanation:
The given functions are:



We compose F(x) and G(x) to get:






Hence G(x) is not an inverse of F(x).
We now compose H(x) and G(x).



We simplify to get:


Since
, H(x) is an inverse of F(x)
