Ответ:
Option A - .
Step-by-step explanation:
Given : The graph of and the graph of F(x) which is changed somewhat.
To find : The equation of graph F(x)
Solution :
Since, According to the given statement we get F(x) by doing some changes in G(x).
In the graph, it seems that F(x) is shifting vertically downward by 4 unit than G(x).
When the function is shifted to vertically downward then
i.e, f(x) → f(x)-b ⇒ f(x) shifted downward by b unit.
We also see that the graph of F(x) is reflected over x-axis.
Reflection over x-axis meas y=-x i.e, signs are changed.
So,
Therefore, Option A is correct.
The graph is .

x / 2 + 2 = 2x / 3
The value of x from the equation is 12. Thus, the capacity of the container is 12 gallons.
