Answer:
The correct option is 3.
Step-by-step explanation:
The vertex form of a parabola is
.... (1)
where a, h, and k are integers, and interpret the vertex of f(t). (h,k) is the vertex of the parabola.
The given function is
It can be written as
If an expression is defined as 
, then we need to add 
to make it perfect square.
In the expression 
the value of b is -2. So, we nned to add and subtract 
in the parenthesis.
.... (2)
The vertex form of the parabola is .
From (1) and (2), we get h=1 and k=2. It means the vertex of the parabola is (1,2). Vertex of upward parabola is point of minima. So the minimum height of the roller coaster is 2 meters from the ground.
Therefore the correct option is 3.

1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1
