Answer:
![4x+9+4x^2](https://tex.z-dn.net/?f=4x%2B9%2B4x%5E2)
Step-by-step explanation:
The given functions are:
and
We want to find
.
Recall that:
![(f+g)(x)=f(x)+g(x)](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3Df%28x%29%2Bg%28x%29)
We substitute the functions to get:
![(f+g)(x)=4x+9+4x^2](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D4x%2B9%2B4x%5E2)
We now write in standard form to obtain:
![(f+g)(x)=4x^2+4x+9](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D4x%5E2%2B4x%2B9)
Answer:
-2
Step-by-step explanation:
y=-1-2x
by substitution
-1-2x=1/2x+4
5/2x=-5
x=-2
