Answer:
The equations that represent the reflected function are
![f(x)=5(\frac{1}{5})^{-x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-x%7D)
![f(x)=5(5)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%285%29%5E%7Bx%7D)
Step-by-step explanation:
The correct question in the attached figure
we have the function
![f(x)=5(\frac{1}{5})^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7Bx%7D)
we know that
A reflection across the y-axis interchanges positive x-values with negative x-values, swapping x and −x.
therefore
![f(−x) = f(x).](https://tex.z-dn.net/?f=f%28%E2%88%92x%29%20%3D%20f%28x%29.)
The reflection of the given function across the y-axis will be equal to
(Remember interchanges positive x-values with negative x-values)
![f(x)=5(\frac{1}{5})^{-x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-x%7D)
An equivalent form will be
![f(x)=5(\frac{1}{5})^{(-1)(x)}=5[(\frac{1}{5})^{-1})]^{x}=5(5)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B%28-1%29%28x%29%7D%3D5%5B%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-1%7D%29%5D%5E%7Bx%7D%3D5%285%29%5E%7Bx%7D)
therefore
The equations that represent the reflected function are
![f(x)=5(\frac{1}{5})^{-x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-x%7D)
![f(x)=5(5)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%285%29%5E%7Bx%7D)

Answer:
![f(-1) = -2](https://tex.z-dn.net/?f=f%28-1%29%20%3D%20-2)
Step-by-step explanation:
Given
The attached graph
Required
![f(-1)](https://tex.z-dn.net/?f=f%28-1%29)
This is the point where
![x = -1](https://tex.z-dn.net/?f=x%20%3D%20-1)
On the attached graph;
when ![x = -1](https://tex.z-dn.net/?f=x%20%3D%20-1)
Hence:
![f(-1) = -2](https://tex.z-dn.net/?f=f%28-1%29%20%3D%20-2)
First see you can factor out 4. What is left is x^2 + 6x - 16.
That can be factored as (x+8)(x-2) so the total factorization is
4(x+8)(x-2)
