Value of this function as n approaches infinity

Click For Summary
SUMMARY

The limit function f(x) = lim _{n->\infty}(x{n})/(1+x{n}) evaluates to 1 when x > 1, 0 when 0 < x < 1, and 1/2 when x = 1. The reasoning behind this conclusion is that as n approaches infinity, the highest power of n in both the numerator and denominator dominates, leading to the simplification x^n/x^n = 1. Therefore, the correct interpretation of the limit is crucial for understanding the behavior of the function as n approaches infinity.

Homework Statement


f(x) = lim _{n-&gt;\infty}(x{n})/(1+x{n})


Homework Equations



Suppose that x=1

The Attempt at a Solution



Wouldnt f(x) = 1/2? Because 1^n = 1, so the denominator is 2. The solution says that f(x)=1. Why is that?

Hi
yes the answer is f(x)=1 because both of them have the highest power of n so based on that if you have the same power you just take the cofficient which is one.
x^n/x^n = 1 when the limit goes to infinity.
 
Yes f(1) is 1/2. The limit is 1 if x > 1 and 0 for x between 0 and 1.
