Consider the functions f(x)=-9x-1 and g(x)= (a) Find f(g(x)). (b) Find g(f(x)). g(x+1). (c) Determine whether the functions f and g are inverses of each other. (a) What is f(g(x))? f(g(x))=x (Simplify your answer.) Give any values of x that need to be excluded from f(g(x)). Select the correct choice and, if necessary, fill in the box within your choice. A. x (Use a comma to separate answers as needed.) B. No values should be excluded from the domain. (b) What is g(f(x))? g(f(x)) = (Simplify your answer.)
