Question: Consider the equation=1 and the relation ( x, y ) R (0, 2), where R is read as has distance 1 of. For example, (0,

Consider the equation=1 and the relation "(x, y)R(0, 2)", whereRis read as "has distance 1 of".

For example, "(0, 3)R(0, 2)", that is, "(0, 3) has distance 1 of (0, 2)". This relation can also be read as "the point (x, y) is on the circle of radius 1 with center (0, 2)". In other words: "(x, y) satisfies the equation= 1,if and only if, (x, y)R(0, 2)".

Answer the following in your discussion.

Does this a relation betweenxandy?Can the variablexbe expressed as a function ofy, like )?Can the variableybe expressed as a function ofx, like = )?If these are possible, then what will be the domains these two functions?What are the graphs of these two functions?

Are there points on the x-axis and on y-axis that are (0, 2) by means ofR?
