What happens to $$f(n)$$ as $$n$$ increases?

Understanding the Function $$f(n)$$

The given function is $$f(n)=\left|\left(\frac{11}{12}+\frac{7}{12} i\right)^n\right|$$. This function involves complex numbers and absolute value. To understand what happens to $$f(n)$$ as $$n$$ increases, we need to break down the function and analyze its components.

Complex Numbers and Absolute Value

A complex number is a number that can be expressed in the form $$a+bi$$, where $$a$$ and $$b$$ are real numbers, and $$i$$ is the imaginary unit, which satisfies $$i^2=-1$$. The absolute value of a complex number $$z=a+bi$$ is defined as $$|z|=\sqrt{a^2+b2}$$.

In the given function, the complex number is $$\frac{11}{12}+\frac{7}{12} i$$. The absolute value of this complex number is $$\left|\frac{11}{12}+\frac{7}{12} i\right|=\sqrt{\left(\frac{11}{12}\right)^{2+\left(\frac{7}{12}\right)}2}=\sqrt{\frac{121}{144}+\frac{49}{144}}=\sqrt{\frac{170}{144}}=\frac{\sqrt{170}}{12}$$.

Properties of Exponents

When dealing with exponents of complex numbers, we need to consider the properties of exponents. Specifically, we need to consider the property that states $$|z^n|=|z|n$$, where $$z$$ is a complex number and $$n$$ is a positive integer.

Using this property, we can rewrite the function $$f(n)$$ as $$f(n)=\left|\left(\frac{11}{12}+\frac{7}{12} i\right)^n\right|=\left|\frac{11}{12}+\frac{7}{12} i\right|^{n=\left(\frac{\sqrt{170}}{12}\right)}n$$.

Analyzing the Function

Now that we have rewritten the function $$f(n)$$, we can analyze its behavior as $$n$$ increases. Since the function is an exponential function with a base of $$\frac{\sqrt{170}}{12}$$, which is less than 1, we can expect the function to decrease as $$n$$ increases.

Conclusion

Based on our analysis, we can conclude that as $$n$$ increases, $$f(n)$$ decreases. This is because the function is an exponential function with a base of $$\frac{\sqrt{170}}{12}$$, which is less than 1.

Comparison with Options

Now that we have analyzed the function $$f(n)$$, we can compare our results with the options provided.

Option A states that as $$n$$ increases, $$f(n)$$ remains constant. This is incorrect, as we have shown that $$f(n)$$ decreases as $$n$$ increases.
Option B states that as $$n$$ increases, $$f(n)$$ decreases. This is correct, as we have shown that $$f(n)$$ decreases as $$n$$ increases.

Final Answer

Based on our analysis, we can conclude that the correct answer is:

B. As $$n$$ increases, $$f(n)$$ decreases.
