First, you subtract 5h from both sides.
-9 = -16 + h
Then, you add 16 to both sides.
7=h
So, h = 7.
The vertex is when x=-b/2a, which is also the line of symmetry.
in this case, b=6, a=3, so x=-6/6=-1
when x=-1. y=3-6-1=-4
another way to do it is to write the equation into vertex form by making a square:
3x²+6x-1
3(x²+2x-1/3)
3(x²+2x+1-1-1/3))
3(x²+2x+1-4/3))
notice the bold part makes a square:
3(x+1)²-4
Either way,
the vertex is (-1, -4)
the axis of symmetry is x=-1
the coefficient of x² is 3, a positive number, so this parabola opens upward. the function has a minimum value of y=-4
the range is all real number larger than -4
Answer: it is 0.

Dispenser C is your answer
16/25 x 4/4 = 64/100
64/100 = 0.64, or 64%
Your answer is Dispenser C
