Answer:
A. No, the graph fails the vertical line test.
Step-by-step explanation:
First let's see what a vertical test is.
It is a test used to find the whether the given graph is a function or not.
We draw a vertical line on the given graph, if the line cuts the graph at only one point of the graph, then it is a function.
If the line cuts the graph at more than one point, then it is not a function.
So, if we draw a vertical line on the given circle, the vertical line cuts the graph at two points of the graph.
Therefore, it is not a function and it is fails the vertical test.
Answer is A. No, the graph fails the vertical line test.

Step-by-step explanation:
1.
Cot is the trigonometric ratio defined by "adjacent" over "opposite". <em>So, adjacent = 2 and opposite = 3.</em>
By pythagorean theorem, we have the "hypotenuse" as
Csc is defined as the trig ratio "hypotenuse" over "opposite". <em>We know the sides, so Csc =
</em>

<em>First answer choice is right.</em>

2.
By definition, Csc is the inverse of Sine
. <em>If given the value of sin theta, to find value of csc theta, we take the reciprocal of it. Hence:</em>
Third answer choice is right.
3.
By definition tan and cot are inverse of each other. <em>So the value of tan is the reciprocal of the value of cot.</em> We can simply "flip" the value of tan theta to get the value of cot theta. Hence:
Third answer is right.
