Answer
The given circle has:
center at (0, 4)
radius = 1 unit
Refer to the attached image for the graph.
Work Step by Step
RECALL:
The standard equation of a circle whose center is at (h, k) and radius $r$ is:
$(x-h)^2+(y-k)^2=r^2$
The given equation is similar to the standard form given above.
Thus, the given equation represents a circle with center at (0, 4) and
$r^2=1
\\r=1$
Therefore, the given circle has:
center at (0, 4)
radius = 1 unit
Plot the points $(-1, 4), (1, 4), (0, 5), \text{ and } (0, 3)$ then connect them using a curve to form a circle.
Or, use a graphing calculator to have the graph attached in the answer part above.
