Answer:
0, 5, 7
Step-by-step explanation:
You just follow the rule written at the top, if the left column is x, the right column is x/6. For example, if the right column is 0, the left would be 0/6, which is 0.

Answer:
Last Graph (4th one)
Step-by-step explanation:
The equation given is ![A(x)=400*b^x + 0\\A(x) = 400b^x](https://tex.z-dn.net/?f=A%28x%29%3D400%2Ab%5Ex%20%2B%200%5C%5CA%28x%29%20%3D%20400b%5Ex)
Since we want increase of 25%, the value of b would be 1.25, so we have:
![A(x)=400(1.25)^x](https://tex.z-dn.net/?f=A%28x%29%3D400%281.25%29%5Ex)
The graph should be increasing so we can immediately eliminate 2nd and 3rd graphs since they are clearly decreasing. We now have to choose between 1st graph and 4th graph.
<u>1st graph:</u>
Let's take the point (-20,30)
![A(x)=400(1.25)^{-20}\\A(x)=4.65](https://tex.z-dn.net/?f=A%28x%29%3D400%281.25%29%5E%7B-20%7D%5C%5CA%28x%29%3D4.65)
<u>2nd graph:</u>
Let's take the point (-20,4.5)
![A(x)=400(1.25)^{-20}\\A(x)=4.65](https://tex.z-dn.net/?f=A%28x%29%3D400%281.25%29%5E%7B-20%7D%5C%5CA%28x%29%3D4.65)
hence, this makes sense. So the correct graph is 4th one.
