It's an equation of a circle with the center (4, 0) and the radius r = 2.

Step-by-step explanation:

It's an equation of a circle.

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have:

[tex](x-4)^2+y^2=4\\\\(x-4)^2+(y-0)^2=2^2\Rightarrow(4,\ 0),\ r=2[/tex]
