...The highest point on the other branch is(-1,-2)
(i) Use the graph to solve the following equations, showing your method clearly
The equation (x-1)^2 +y^2=4 represents a circle. Find in exact form the coordinates of the points of intersection of this circle with the y-axis
i) State the radius and the coordinates of the centre of this circle.
Explain how these can be used to deduce from the graph that this circle touches one branch
of the curve y=x+1/x but does not intersect with the other
My test is on monday need help thorugh past papers pleaseeee thanks in advance
