(x+10)^2 + (y-5)^2 > 1

Question

Graph

I need the vertex the center and the limit

Answer 1

This is based on the equation of a circle centre (-10,5) and radius >1. So the graph consists of concentric circles extending indefinitely outwards. Just a few circles are shown in the picture:

The most central circle represents the lower limit. All the rest of the x-y plane outside this circle is completely filled with concentric circles radiating from (-10,5) without limit. The circumference of the innermost circle is the inner boundary and has a radius of 1.
