Let f be a function such that StartFraction x squared minus x Superscript 4 Baseline Over x squared EndFraction ≤ f(x) ≤ One-fourth x cubed for all –2 ≤ x ≤ 2. What is Limit of f (x) as x approaches 0?

The limit is 0.
The limit is 1.
The limit does not exist.
The limit cannot be found because f(x) is unknown.
