y=2sin(x) and y=sin(x) using words only how could I compare these functions?

Can you highlight the answers and give me a detailed explanation. Please use paper if possible.

I need help with this problem

PLS HELP ASAP ON ALL ASKED QUESTIONS

Since the function y=cosx and y= cosx are inverse functions, why is cos not equal to -- 2 Explain your reasons clearly.

If you are not given the graph of a cosine function f(x) however its maximum and minimum are 3π given which are A A(,112) and B -,28). Are you able to tell the period and amplitude of 2 f(x)? If yes, write the period and amplitude; if no, explain your reasoning.

Can you please answer this question and show all of the steps and say the correct letter
