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.!
