If the graph in red is $y = 3\sin(x)$ , what could the graph in blue be?

What's the minimum possible value of $y$ for

$y = -5 \sin(2x - \pi) - 2 ?$

The $\arccos$ function is typically defined by taking the inverse of a cosine with a domain of $[0, \pi)$ . What would be the effect if the inverse was of a cosine with a domain of $[0, 2\pi)$ instead? (The graphs below may help.)

Graph of $f(x) = \cos(x)$ :

Graph of $f(x) = \arccos(x)$ :

The interval depicted is 0 to $4 \pi$ . Which of these could not represent the graph above?
