Which of the following is true for f(x) = –2sin(x) – 3?
Finger [1]

Answer: Option C is correct!

Step-by-step explanation:

The range of function is [-1,-5]  . so first option is incorrect.

Since graph of the function f(x)=-2sin(x) is shifted down by 3 because of -3

therefore  option B is incorrect.

Period of the given function is 2pi because here b =1 and period of sinx function is given by \frac{2\pi }{b} therefore option  D is also incorrect

Period of the function f(x) is always  absolute value number in front  of sinx  which is given to be  2 here therefore option C is correct.!
