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

y = -4.4 \sin (x)

y = -1.6 \sin(x)

y = 4.4 \sin (x)

y = 1.6 \sin (x)

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

There would be a possible division by zero The arccosine would no longer be a function There would be inputs to the function with no output

Starting from the basic definition of the tangent function, which is these facts most directly implies the tangent graph has a vertical asymptote at $\frac{\pi}{2}$ ?

\tan(\frac{\pi}{4}) = 1

\sin(\frac{\pi}{2}) = 1

\cos(\frac{\pi}{2}) = 0
