Answer:
Here:
Explanation:
23. f(x) =
and g(x) =

24. f(x) =
and g(x) =

28. f(x) =
and g(x) =

29. f(x) =
and g(x) =

Basically, you try to find a function contained inside a function if that makes sense. For example in question 23, g(x) itself is a function =
. Same with f(x) =
. In this case, when we try to fo f(g(x)), we are basically replacing x in the f(x) function by the equation in g(x). Hope this makes sense.
