What is the range of the function y = 1 + 2sin(x − 3.14)?

Hello:
-1 ≤ sin(x- π ) ≤ 1 
-2 ≤ 2 sin(x- π ) ≤2 
1-2 ≤ 1+ 2 sin(x- π ) ≤ 1 +2
-1≤y≤3
the range is : [-1 : 3 ]

Just a second zzz

Yes, that is the correct formula. to solve this problem given the number of years, plug in the number of years for t and plug the whole thing into the
