Step-by-step explanation:
For a function whose formula is in this pattern:
![y=A\sin\left(B(x-C)\right)](https://tex.z-dn.net/?f=y%3DA%5Csin%5Cleft%28B%28x-C%29%5Cright%29)
Amplitude: ![|A|](https://tex.z-dn.net/?f=%7CA%7C)
Period: ![\frac{2\pi}{B}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%7D%7BB%7D)
Phase Shift: C
In this question, ![A=4,\,B=2,\,C=\frac{3\pi}{4}](https://tex.z-dn.net/?f=A%3D4%2C%5C%2CB%3D2%2C%5C%2CC%3D%5Cfrac%7B3%5Cpi%7D%7B4%7D)
Amplitude: 4
Period: ![\frac{2\pi}{2}=\pi](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%7D%7B2%7D%3D%5Cpi)
Phase Shift: ![\frac{3\pi}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cpi%7D%7B4%7D)
There is no vertical shift, so the midline is the x-axis whose equation is y = 0.
Also, because there is no vertical shift, the maximum is 4 and the minimum is -4.
The graph is attached.
I plugged it into my calculator and I got 1,870.
