Answer:
2
Step-by-step explanation:
The limit of the left side as x approaches ∞ is (4/2)e^(x-x) = 2.
The limit of the right side as x approaches ∞ is 2√(x/x) = 2.
The left side approaches this asymptote from below; the right side from above. This squeezes f(x) to an increasingly smaller range around 2.
The limit of f(x) is 2 as x → ∞.
