Answer: D
Step-by-step explanation:
Evaluating the functions at x = 0,
A) y = -cos(0) + 2 = -1 + 2 = 1
B) y = cos(0) + 2 = 1 + 2 = 3
C) y = -sin(0) + 2 = 0 + 2 = 2
D) y = sin(0) +2 = 0 + 2 = 2.
Now, we just need to determine if it is C or D.
Since after x=0, the graph increases then decreases, we know the coefficient of sin x must be positive, and thus the answer is D.
