You need to know how many inches are in 1 foot.
1 foot / 12 inches
There are 12 inches in 1 foot. So...
72 inches <span>× 1 foot / 12 inches
72/12 = 6 feet
There is your answer.

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
Hope could help :)
