the equation y= e^x(px^2 +qx+r) exists such that the tangents at x=1 and x=3 are parrallel to the x-axis. The coordinates with points(0,9) is on the curve find p, q and r. PLZ HELP GUYS>

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

goog may be able to you find that answer
