Question 111223: I am graphing a parabola and I have all of my points done but I'm having a problem getting the x & y vertex's....the equation is 3x²-x-1=0 ...I have 1.5 for x but I'm told this is wrong and I have no idea how to solve it for the y vertex. Please help!
Thanks so much!

You can put this solution on YOUR website! Y=3X^2-X-1
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = 3x^2 -x -1).
x=1/6 answer for the x coordinate of the vertex.
y=-13/12 the y coordinate of the vertex.
