Answer:
f(x)= -x^2
Step-by-step explanation:
the reflection adds a negative sign to the equation
sin 3 x = sin ( 3 x + 2 π ) = sin [ 3 ( x + 2 π/ 3 ) ] = sin 3 x
This means "after the arc rotating three time of ( x + ( 2 π /3 ) ) , sin 3x comes back to its initial value"
So, the period of sin 3x is 2 π /3 .

Answer:
12.6
Step-by-step explanation:
To find the area of a circle, you need to use the formula ![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
We have
, so we need to plug it into the formula.
![A=\pi (2)^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20%282%29%5E%7B2%7D)
![A=\pi (4)](https://tex.z-dn.net/?f=A%3D%5Cpi%20%284%29)
![A=12.5663706...](https://tex.z-dn.net/?f=A%3D12.5663706...)
Since we need to round to the nearest tenth, your final answer should be ![12.6](https://tex.z-dn.net/?f=12.6)
