Ok, so you want to substitute g and f in these equations so the f(x) = 2x+3x2-5 is equal to 10+6-5 or 11. The other equation is equal to 19. For the explanation put " I found this answer by substituting the given values for the variables in the equation". Your Welcome!
Given:
The minimum and maximum distance that the dog may be from the house can be found by using the equation:
To find:
The minimum and maximum distance that the dog may be from the house.

We have,
It can be written as:
Adding 500 on both sides, we get
Now,
and 
and 
The minimum distance is 492 meters and the maximum distance is 508 meters.
Therefore, the correct option is C.
