Find the range of the function y=-3sin(3x)-2
I know that I can plug it in to my graphing calculator but I'm not sure like how exactly to tell what the range is =(.
My professor wants it in union/infinity form eg. (-Infinity,-2]U(4,Infinity) which makes it even more confusing to me.
Could someone please help?
Much appreciated.
