4 and 5 because it talks about how
Answer:

Step-by-step explanation:
The given expression is

The tangent of -1 is defined, it's around -0.02.
The tangent is a trigonometric function with a period of
, where each period is separated by a vertical asymptote which indicates that the function is not determined through all its domain, that's what the question refers to when it says "if is undefined, enter undefined".
However, at
, the tangent is determined, that means, there's no asymptote on that coordinate, that's why it has a "determined value", which is -0.02 approximately.
