Answer:
Step-by-step explanation:

Question 1:
For this case we must find
knowing that:

By definition we have that, be two functions f (x) and g (x), then the composite function of f with g is:
![(g_ {0} f) (x) = g [f (x)]](https://tex.z-dn.net/?f=%28g_%20%7B0%7D%20f%29%20%28x%29%20%3D%20g%20%5Bf%20%28x%29%5D)
In this case, they ask us for the function composed of g with f:
![(f_ {0} g) (x) = f [g (x)]](https://tex.z-dn.net/?f=%28f_%20%7B0%7D%20g%29%20%28x%29%20%3D%20f%20%5Bg%20%28x%29%5D)
So, we have:

ANswer:

Question 2:
For this case, we must find the inverse function of
, given by: 
To do this, replace g(x) with y:

We exchange variables:

We solve for "y":

Replace "y" with 
So, we have:

Answer:

Question 3:
For this case, we have by definition, the domain of a function f (x), is the set of all the values for which the function is defined.
We must find the domain of the following function:

It is observed that the function is not defined for 
Then the domain is given by all the values of x, except 0.
for any integer n
Answer:
All numbers, except
The probability would be 999/1000 that you would not win
Answer:
c=42
Step-by-step explanation:
First you would find out how much you would add to 45 to give you 66. Which is 21. Then you double it, so when you put it over the two it looks like this 42/2. So when you reduce the fraction you get 21. Hence 21+45=66.
Hope this helps!
