We have the function:
![f(x)=2sin(3x)](https://img.qammunity.org/2023/formulas/mathematics/college/hur8khcd346vze5os1hld86b8xyz0o15vs.png)
For a sine wave, the range of the function is dependent on the coefficient of the sine function; in this case, 2 is the coefficient of the function. This means that the lowest point of the wave occurs at -2 and the highest point on the wave occurs at 2. The range of the function is given below:
