Solution

To evaluate the limit of the function as x approaches infinity, we can use the rule of thumb that says: for a rational function (a ratio of two polynomials), the limit as x approaches infinity is determined by the highest powers of x in the numerator and the denominator.

Here, the highest power of x in the numerator is 3 (from the term x^3) and in the denominator is 4 (from the term 25x^4).

Since the highest power of x is greater in the denominator than in the numerator, the limit of the function as x approaches infinity is 0.

So, lim (x→∞) (x^3 + 25) / (x^4 + 5) = 0.
