For each of the following, make a sketch of all complex numbers in the complex plane which satisfy the given expression.

- The complex numbers such that are a solid disk of radius 1 centered at the origin:

- We have
The plot in the complex plane is a vertical line at ,

- We have
The plot in the complex plane is a horizontal line at .

- We have
The plot is a vertical line at .

- We have
The plot is a horizontal line at .

- We have
The plot is a circle of radius one centered at ,

I think the last one should say y=+-sqrt(x(2-x))
