Answer:

  (a)  1

Step-by-step explanation:

For large variable magnitude, the value of a rational function approaches the ratio of the highest-degree terms of the numerator and denominator*. Here, that is ...

  x/x = 1

f(x) approaches 1 as x approaches infinity.

__

* The function approaches the line or curve defined by the quotient. (The remainder is ignored in this case.) Here, f(x) = 1 + 3/(x-3), so the quotient is the constant 1.
