Answer:
![f(x)=x+3](https://tex.z-dn.net/?f=f%28x%29%3Dx%2B3)
![g(x)=\frac{2}{x^2}](https://tex.z-dn.net/?f=g%28x%29%3D%5Cfrac%7B2%7D%7Bx%5E2%7D)
Step-by-step explanation:
we are given
![y=\frac{2}{x^2}+3](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7Bx%5E2%7D%2B3)
Since, we have to identify f(x) and g(x)
where g(x) is inner function
Let's assume
![g(x)=\frac{2}{x^2}](https://tex.z-dn.net/?f=g%28x%29%3D%5Cfrac%7B2%7D%7Bx%5E2%7D)
so, we get
![y=g(x)+3](https://tex.z-dn.net/?f=y%3Dg%28x%29%2B3)
we know that
y=f(g(x))
so, we can also write as
![f(g(x))=g(x)+3](https://tex.z-dn.net/?f=f%28g%28x%29%29%3Dg%28x%29%2B3)
now, we can replace g(x) as x
we get
![f(x)=x+3](https://tex.z-dn.net/?f=f%28x%29%3Dx%2B3)
so, we get
![f(x)=x+3](https://tex.z-dn.net/?f=f%28x%29%3Dx%2B3)
![g(x)=\frac{2}{x^2}](https://tex.z-dn.net/?f=g%28x%29%3D%5Cfrac%7B2%7D%7Bx%5E2%7D)
I just did this I’m gonna have my friend come and answer this for u
Answer:
Step-by-step explanation:
7x - 5x = -11
2x = -11
x = -11/2
