Basically we follow the piece wise function.
Explanation of piece wise function
_
| -x + 7, x ≤ 1
f(x) = | x³ - 5, -1 < x < 2
| 3 , x ≥ 2
_
When x in f(x) is less than or equal to 1 than f(x) = -x + 7
When x in f(x) is greater than -1 but less than 2 than f(x) = x³ - 5
When x in f(x) is greater than or equal to 2 than f(x) = 3

Now lets look back at the question
We want to find f(5,000,000,000,000,000)
Looking at the piece wise function we see that the x in f(x) (5,000,000,000,000,000) follows x ≥ 2 as 5,000,000,000,000,000 is greater than 2. When x is greater than or equal to 2, f(x) = 3, hence f(5,000,000,000,000,000) = 3
