(1) translate the parabola Y1 = 2x2 two units to the right to get the parabola Y2 Ask 2010 Zhejiang Yiwu high school entrance examination question 16 very detailed analysis? 16. (1) translate the parabola Y1 = 2x2 two units to the right, and get the result For the image of parabola Y2, then y2 = ■; (2) As shown in the figure, P is a moving point on the symmetry axis of the parabola Y2, The straight line x = t is parallel to the Y axis, and is respectively parallel to the straight line y = x The parabola Y2 intersects at points a and B. If △ ABP is a parabola Or an isosceles right triangle whose point B is a right vertex If the value of T is sufficient, then t = 0 can be found in the graph.

(1) The parabola Y1 = 2x2 moves 2 units to the right, so y = 2 (X-2) 2 = 2x2-8x + 8; so the analytical formula of the parabola Y2 is y2 = 2x2-8x + 8. (2) from (1), we know that the symmetry axis of the parabola Y2 is x = 2, so the abscissa of point P is 2; when x = t, the straight line y = x = t, so a (T, t); y2 = 2x2-8x + 8 = 2t2-8t + 8, so B
