find the vertex and graph of y=.3x2+1.8x2

college math  Damon, Sunday, March 7, 2010 at 8:31pm
y = 0.3 x^2 + 1.8 x  2 ???
.3 x^2 + 1.8 x = y+2
x^2 + 6 x = (10/3)y + 20/3
x^2 + 6 x + 9 = (10/3) [y + 2/3 + 2.7/3]
(x+3)^2 = (10/3) [ y + 4.7 ]
(3, 4.7) vertex
axis of symmetry is x = 3
upright, holds water
