出门在外也不愁将抛物线y=-3xƝ5经过怎样的平移使它经过点o(0,0)和点a(1,9)?_作业帮

将抛物线y=-3xƝ5经过怎样的平移使它经过点o(0,0)和点a(1,9)?
将抛物线y=-3xƝ5经过怎样的平移使它经过点o(0,0)和点a(1,9)?
解设平移后的抛物线为y=-3x^2+bx+c由平移后的抛物线经过点o(0,0)和点a(1,9)知0+0+c=0-3+b+c=9解得b=12,c=0故平移后的抛物线为y=-3x^2+12x由y=-3x^2+12x=-3(x-2)^2+12该函数的顶点为（2,12）故由抛物线y=-3x^2向右平移2个单位,然后向上平移12个单位,即得到函数y=-3x^2+12的图像,该图像经过点o(0,0)和点a(1,9)
