In the function f(x), x is replaced with 3x.

 

f(x)=12sin(x)−4

What effect does this have on the graph of the function?

 

I am assuming it is vertically stretched by 1/3, not sure though

really? I was asuming that it was getting stretched because I saw more humps...compressed usually means less humps?

Look at the graphs here, L2R  : https://www.desmos.com/calculator/eowgcnrrnu

 

Note that the second graph is a horizontally compressed version of the first

Imagine it is like a spring      stretch it .....coils further apart ...less humps  

                                              COMPRESS IT....coils closer together...more humps
