Answer:
The answer to your question is it is stretched
Step-by-step explanation:
See the graph below
As you can see in the graph, the amplitude of the function y = sinx goes from -1 to 1, if the amplitude if higher, then it will be stretched in the example of this problem, the amplitude is 3, so it goes from -3 to 3.
If the amplitude were lower than 1, for example, 0.5, the graph will be compressed.
