Analytical formula of (1) parabola: Because point A (-3,0) and point B are symmetrical about x=- 1, so point B (1, 0), again,

C(0, -2), bring y = ax 2+bx+c to get y = 2/3x 2+4/3x-2.

(2) As an auxiliary line AP, it is obvious that AP is equal to BP, because △APB is an isosceles triangle. So the perimeter of △PBC is equal to AP+PC+CB, and CB remains unchanged, so as long as AP+PC is the smallest. Obviously, the linear distance between point A and point C is the shortest, so we just need to find the intersection of AC and x=- 1 symmetry axis. The equation of a straight line through AC is

Y=-2/3(x+3), and when x=- 1, y=-4/3.
