Answer:
I'm not entirely sure but I got:
![\frac{ {4x}^{3} + 3 }{(2x - 1)( {x}^{2} + x)( {2x}^{2} - 3x + 1) }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7B4x%7D%5E%7B3%7D%20%2B%203%20%7D%7B%282x%20-%201%29%28%20%7Bx%7D%5E%7B2%7D%20%20%2B%20x%29%28%20%7B2x%7D%5E%7B2%7D%20-%203x%20%2B%201%29%20%7D%20)

Hello there!
4-3x=5
4=5+3x
4-5=3x
-1=3x
-1/3=x

Answer:
(f - g)(x) = f(x) - g(g) = (3x + 1) - (x2 - 6) = -x^2 + 3x + 7
Step-by-step explanation:
Answer:
![(f\circ g )(x) = -4](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%20%29%28x%29%20%3D%20-4)
Step-by-step explanation:
We have
![(f\circ g )(x) := f(g(x))](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%20%29%28x%29%20%3A%3D%20f%28g%28x%29%29)
Therefore,
![f(x)=x+1 \implies f(x)=g(x)+1](https://tex.z-dn.net/?f=f%28x%29%3Dx%2B1%20%5Cimplies%20%20f%28x%29%3Dg%28x%29%2B1)
So,
![(f\circ g )(x) = 5x + 1](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%20%29%28x%29%20%3D%205x%20%2B%201)
For ![x = -1:](https://tex.z-dn.net/?f=x%20%3D%20-1%3A)
![(f\circ g )(x) = 5(-1) + 1 = -5+1=-4](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%20%29%28x%29%20%3D%205%28-1%29%20%2B%201%20%3D%20-5%2B1%3D-4)
