β(0, 3) R (0, 2)β, that is, βthe point (0, 3) is 1 unit distance away from the point (0, 2)β. This relation can also be read as βthe point (x, y) is on the circle of radius 1 with center (0, 2)β. In other words: β(x, y) satisfies this equation x^2+(y-2)^2=1, if and only if, (x, y) R (0, 2)β.
Does this equation determine a relation between x and y? Meaning, is there a relation between x and y to have the pair (x, y) related to the pair (0, 2). Can the variable x be seen as a function of y, like x=g(y)? Can the variable y be expressed as a function of x, like y= h(x)? If these are possible, then what will be the domains for these two functions? What are the graphs of these two functions?
Are there points on the coordinate axes that relate to (0, 2) by means of R?
