Question: Consider the equation x2 + (y-2) 2 = 1 and the relation (x, y) R (0,2), where the R is read as has distance 1
Consider the equation x2 + (y-2) 2 = 1 and the relation (x, y) R (0,2), where the R is read as "has distance 1 of".
Does this equation determine a relation between x and y? Can the variable x be seen as a function of y, and y be seen as a function of x? What are the domains for these two functions? What are the graphs of these two functions? Are there points of the coordinate axes that relate to (0,2) by means of R?
