Hi everyone,

It seems that these composition of functions has given me some problems. I am stuck on one problem set in particular, maybe someone here could help me. The set is as follows:

Use the given functions to answer the following questions. (Enter NONE in any unused answer blanks.)

(a) Evaluate (fog)(x).

(b) Evaluate (gof)(x).

c) Evaluate (fof)(x).

(d) Evaluate (gog)(x).

Thanks in advance for any help.
