Answer:
Step-by-step explanation:
Actually, you have not "given" the domain.
The domain of F(x)=x^2+2 is "the set of all real numbers," because F(x)=x^2+2 is a polynomial.
F(x^2) = (x^2) + 2 = x^4 + 2. Again, this is a polynomial and the domain is "the set of all real numbers."

Answer:
The system has two distinct solutions.
Step-by-step explanation:
The given system of equations are:

and

In order to determine the number of solutions the two equations have, we need to equate the two equations to obtain,

We now group all terms on the left hand side and equate everything to zero.


This is now a quadratic equation in
with
.
At this stage we check the number of solutions using the discriminant.


Since the discriminant is greater than zero, the equation will have two distinct roots.
Therefore the system of equations has exactly two distinct solutions.
If you wish to see these solutions, you can continue as follows;
We factor
to obtain,



When 
Then we have,

When 
Then we have,

See graph
1220*24 = 29,280 per year
multiply that by number of years until he retires:
761280 / 29280 = 26 years
292800 / 29280 = 10 years
the other 2 arent even years so it should be one of those 2. I would say the larger number
