2. Let f be the function given by f(x)=x +3x-x+2. (A) The tangent to the graph of fat the point P = (-2,8) intersects the graph of f again at the point Q. Find the coordinates of the point Q. (B) Find the coordinates of point R, the point where f'(x)=0. (C) Show that the segment QR divides the region between the graph of fand its 16 tangent at P into two regions whose areas are in the ration of 11 "(-2,8)`
