Answer:

the first one on the bottom

Step-by-step explanation:

There is a little trick to find out if it is a function or not. This trick is called the vertical line test. if you can scan the figure with a virtual line and it does not touch more than one side of the figure at one time then it is a function. if it touches more than one side or line of the figure it is not a function.

Hi!

Let's first expand the cotangent of theta.

You'll probably know that tangent will be "y/x", or $\frac{sin(x)}{cos(x)}$ , and cotangent is the reciprocal of this, meaning that it is "x/y" or $\frac{cos(x)}{sin(x)}$ .
