For this case we have the following functions:

We must find f (g (x)). So:

Finally we have to:

For the function to be defined the denominator must be different from 0. That is x different from -3.

Answer:
C.
Step-by-step explanation: im pretty sure because if you look at Ed its 5 and then if you add the same sides twice its 10 hopefully im right
Answer:
2x(3x+7)
Step-by-step explanation:
factor 2x out of 6x^2+14x
2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000
compare
20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C
we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200
answer is C
