Question
Evaluate the following limit, writing your answer as either a number or using inf for ∞ if needed.lim𝑥→∞𝑥3+25𝑥4+5=
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.
