Answer:
A. 
B. 
C. 
D. 
Step-by-step explanation:
A. To solve the first part of the problem we must replace 
in the function 
So:
B. In part B we must find the inverse function of
To find the inverse function do 
Now clear the variable x.
Replace x with y.
Finally
C. Now we take the inverse function found above and replace
D. Now we substitute 
in the original function.
3.
The answers 2 and 4 are incorrect because inserting that ad the missing exponent would create only a trinomial.
-9 is incorrect as it would create something more than a polynomial. 7 is incorrect as, if doing a certain type of division, would result in a larger polynomial.

-4(3m-3)+(-10+8m)
12m+12-1+8m
12m+8m = 20m
+12 -1= +11
answer: 20m+11
*note negative times a negative equals positive and negative times positive is negative
first: you multiply -4 by 3m which is -12m.
second: you multiply -4 by -3 which is +12
third: find the invisible which is 1. (located right here: +(1) (-10+8m)
fourth: multiply invisible 1 by -10 which is -10
fifth: multiply invisible one by +8m which is +8m
sixth: combine like terms
seventh: answer
The answer is 5x-5that is the answer
