the graph of y=x^2 + 2x + 9 is shifted 1 unit to the left and 3 units downward... thank you for any help!!!! Solution Graph is shifted 1 unit to the left and 3 units downward. So the x coordinate of each point on the graph will be reduced by 1 unit and the y coordinate of each point on the graph will be reduced by 3 units. So we need to replace x by x-1 and y by y-3. so the equation of shifted graph is y-3 = (x-1)2 +2(x-1)+9 y-3 = x2-2x+1+2x-2+9 y =x2+11.
