Determine the following limits at infinity.

lim x→∞ (5 + 1/x +10/x^2)

검증된 단계별 안내

Identify the terms in the expression: \(5 + \frac{1}{x} + \frac{10}{x^2}\).

Recognize that as \(x\) approaches infinity, \(\frac{1}{x}\) and \(\frac{10}{x^2}\) both approach 0.

Understand that the term \(5\) is a constant and does not change as \(x\) approaches infinity.

Apply the limit to each term separately: \(\lim_{{x \to \infty}} 5 = 5\), \(\lim_{{x \to \infty}} \frac{1}{x} = 0\), and \(\lim_{{x \to \infty}} \frac{10}{x^2} = 0\).

Combine the results of the limits: \(5 + 0 + 0\).

Limits at Infinity

Limits at infinity refer to the behavior of a function as the input approaches infinity. This concept is crucial in calculus for understanding how functions behave for very large values of x, which can help determine horizontal asymptotes and the end behavior of functions.

Dominant Terms

In the context of limits, dominant terms are the parts of a function that have the most significant impact on its value as x approaches infinity. For rational functions, the highest degree terms in the numerator and denominator typically dominate, allowing for simplification when evaluating limits.

Continuous Functions

A continuous function is one where small changes in the input result in small changes in the output. This property is essential when evaluating limits, as it allows us to substitute values directly into the function, provided the function is defined at that point, especially as x approaches infinity.
