x=2 is a vertical line passing through (2,0)
now the graph is symmetrical about that line
so, any original point to left of x=2 will have a reflection on the right hand side
the reflection of the point (1,1) (it is given that the graph passes through (1,1) about the line x=2 is (1+2, 1)
(the x co-ordinate of point (1,1) is at a distance of 1 on left hand side, the reflection should be at a distance of 1 from x=2 on the right hand side hence it will have co-ordinates of (3,1))
Hence since (1,1) is on the graph, (3,1) should also be on the graph
(1/2,2) is on the graph, so will (2+1.5,2)
