Hello there I hope you are having a great day :)
Your Question, -4(2x + 4) > 8x + 64 Solve for X
1) Expand -8x-16>8x+64
2) Add 16 to both sides -8x-16+16>8x+64+16
3) Simplify -8x>8x+80
4) Subtract 8x from both sides -8x-8x>8x+80-8x
5) Simplify -16x>80
6) Multiply both sides -1 (Reverse the inequality) (-16x) (-1) >80 (-1)
7) Simplify 16x<-80
8) divide both sides by 16 16x/16 < -80/16
9) Simplify x < -5
This should be your answer x < -5
Hopefully that helps you :)

Answer: 
Step-by-step explanation:
g°h indicates that you must plug the function h(x) into the function g(x) as you can see below:

Now you must simplify by adding like terms, as following:

By definition you have that:

Theen you must solve for x:

Therefore, the domain is:
{
∈R:
}
Then the answer is
