Question 156166: CAN SOMEONE PLEASE HELP ME WITH THIS PROBLEM:
If f(g(x)) = g(f(x)) = x, then whay can we say about f(x) and g(x)?
a. they are functional inverses of each other
b. f(x) = g(x)
c. f(x) = g(x) = x
d. nothing can be said about f(x) and g(x)
You can put this solution on YOUR website! Remember, if f(x) and g(x) are inverses of one another, then we can say that f(g(x))=x and g(f(x))=x. So this means that the answer is a) they are functional inverses of each other
Note: we know nothing about f(x) and g(x). So we cannot just blindly assume that f(x)=g(x) or f(x)=g(x)=x without some evidence. So this rules our choices b) and c).
