I believe it's 3•3•3-3•3•3•x+3•5•y but I could be wrong :P
12 blue marbles.
white marbles is 5X3=15
so blue is
4X3=12.
It may be misleading because it only tells you those two years, not what happened between those years
To find the coordinates of the vertex, you use the formula x=-b/(2a)
in this case, a is 6, b is 5
x=-5/12
Next, find out the value of y when x is -5/12
y= 6(-5/12)^2 +5(-5/12) -6
y=-23/8
so the vertex is at (-5/12, -23/8)
Please double check the calculation by yourself
