Introduction

In mathematics, the end behavior of a function refers to the behavior of the function as the input values approach positive or negative infinity. Understanding the end behavior of a function is crucial in various mathematical and real-world applications, such as graphing, optimization, and modeling. In this article, we will discuss the end behavior of the function g(x)=1x2g(x)=\frac{1}{x^2}.

The Function g(x)=1x2g(x)=\frac{1}{x^2}

The function g(x)=1x2g(x)=\frac{1}{x^2} is a rational function, where the numerator is a constant (1) and the denominator is a quadratic expression (x2x^2). To understand the end behavior of this function, we need to analyze its behavior as xx approaches positive or negative infinity.

End Behavior as xx Approaches Positive Infinity

As xx approaches positive infinity, the denominator x2x^2 becomes increasingly large. Since the numerator is a constant (1), the value of the function g(x)g(x) will decrease as the denominator increases. However, the function will never actually reach zero, because the denominator will always be positive and will continue to increase without bound.

To determine the end behavior of the function as xx approaches positive infinity, we can use the following limit:

lim⁑xβ†’βˆžg(x)=lim⁑xβ†’βˆž1x2\lim_{x\to\infty}g(x)=\lim_{x\to\infty}\frac{1}{x^2}

Using the properties of limits, we can rewrite this limit as:

lim⁑xβ†’βˆžg(x)=lim⁑xβ†’βˆž1x2=lim⁑xβ†’βˆž1x2β‹…1x2=lim⁑xβ†’βˆž1x4\lim_{x\to\infty}g(x)=\lim_{x\to\infty}\frac{1}{x^2}=\lim_{x\to\infty}\frac{1}{x^2}\cdot\frac{1}{x^2}=\lim_{x\to\infty}\frac{1}{x^4}

Since the denominator x4x^4 approaches infinity as xx approaches infinity, the value of the function g(x)g(x) will approach zero.

End Behavior as xx Approaches Negative Infinity

As xx approaches negative infinity, the denominator x2x^2 becomes increasingly large, just like in the case where xx approaches positive infinity. However, the function g(x)g(x) will behave differently as xx approaches negative infinity.

To determine the end behavior of the function as xx approaches negative infinity, we can use the following limit:

lim⁑xβ†’βˆ’βˆžg(x)=lim⁑xβ†’βˆ’βˆž1x2\lim_{x\to-\infty}g(x)=\lim_{x\to-\infty}\frac{1}{x^2}

Using the properties of limits, we can rewrite this limit as:

lim⁑xβ†’βˆ’βˆžg(x)=lim⁑xβ†’βˆ’βˆž1x2=lim⁑xβ†’βˆ’βˆž1x2β‹…1x2=lim⁑xβ†’βˆ’βˆž1x4\lim_{x\to-\infty}g(x)=\lim_{x\to-\infty}\frac{1}{x^2}=\lim_{x\to-\infty}\frac{1}{x^2}\cdot\frac{1}{x^2}=\lim_{x\to-\infty}\frac{1}{x^4}

Since the denominator x4x^4 approaches infinity as xx approaches negative infinity, the value of the function g(x)g(x) will approach zero.

Conclusion

In conclusion, the end behavior of the function g(x)=1x2g(x)=\frac{1}{x^2} is as follows:

  • As xx approaches positive infinity, the function g(x)g(x) approaches zero.
