damian dilates PQR shown on the coordinate grid with a scale factor of 0.5 centered at the origin. then he translate the 1 unit up and 3 units to the right to from P' Q' R' what are the coordinates of the vertices P' Q' R'

Let x have probability generating function gx (s) and let un generating function u(s) of the sequence uo, u1, satisfies p(x > n). show that the (1- s)u(s) = 1 - gx(s), whenever the series defining these generating functions converge.
