Answer:
No
Step-by-step explanation:
The answer is no, because each value in the domain is associated with exactly one point in the codomain, but a line passing through the circle generally intersects the circle at two points.
This sort of thing is inconvenient, because circles are very important in geometry. Sometimes the points of a circle are described by a relation, given by (x−a)2+(y−b)2=r2, where (a,b) is the center and r is the radius. Because of the squares, there can be two different values of y that make the relation true for various values of x, so the graph of the relation is a circle. I will not suggest taking my answer for i have just started learning functions
