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.!

Y= x+1

y-3 = (-2-3)/(-3-2) (x-2)
y-3 = 1 (x-2)
y = x-2+3
y=x+1

Answer:

x = 67°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for x , that is

x = 180° - (38 + 75)° = 180° - 113° = 67°
