+ Given f(x) = x - 9 and g(x) = x+9, complete the following. (a) Find f(g(x)) and g(f(x)). (Simplify your answers completely.) f(g(x)) = g(f(x)) = (b) What does this tell us about the relationship between f(x) and g(x)? This tells us that f(x) and g(x) are inverse functions of each other. This tells us that f(x) and g(x) are not inverse functions of each other. This tells us that f(x) and g(x) are both even functions. This tells us that f(x) and g(x) are both odd functions. This tells us nothing about f(x) and g(x).
