Question

5. When you calculate f(g(x)) and/or g(f(x)) to determine if they are inverses, whatshould your answer be in order to conclude that f(x) and g(x) are inverses?A. OB. 1C. 10D. x

Answer 1

If function f(x) and g(x) are inverse of each other, then value of function f(g(x)) and g(f(x)) must be equal to x.

So, the value of f(g(x)) and g(f(x)) must be equal to x, in order that f(x) and g(x) are inverses.

Answer: Option D
