27. f(x)-2x-5 g(x)= x+5/2

Which is the "this" which you are proposing is "an inverse function"? Of what function are you proposing that it is "an" (actually, "the") inverse function?

Did the instructions really say "see if this is an inverse function or not"? Or did they say something along the lines of "Determine whether the two listed functions are inverses of each other", or maybe "Prove, algebraically, that the second function is the inverse of the first"?

If the first "minus" sign after the "f(x)" meant to be an "equals" sign? (By the way, as noted previously, as currently posted, the two functions are not inverses.)

What do you mean by your "getting an inverse function for this one"? Which is the "one"? How did you "get"... whatever you got?

Please be complete. Thank you! ;)
