ANSWER
![f(g(x)) = {x}^{2} + 2x](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20)
EXPLANATION
The given functions are:
![f(x) = {x}^{2} - 4](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%204%20)
and
![g(x) = x + 2](https://tex.z-dn.net/?f=g%28x%29%20%3D%20%20x%20%2B%202)
We want to find
![f(g(x)) = f(x + 2)](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20f%28x%20%2B%202%29)
We substitute x+2 wherever we see x in f(x).This implies that;
![f(g(x)) = (x + 2)^{2} - 4](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20%28x%20%2B%202%29%5E%7B2%7D%20%20-%204)
We can rewrite the perfect square term as
![f(g(x)) = (x + 2)(x + 2)- 4](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20%28x%20%2B%202%29%28x%20%2B%202%29-%204)
We expand to get:
![f(g(x)) = {x}^{2} + 2x + 4- 4](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20%2B%204-%204)
This simplifies to
![f(g(x)) = {x}^{2} + 2x](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20)
This is a polynomial function. The domain of this function is the values of x for which the function is defined. Since polynomials are defined for all real values, the domain is all real numbers.
