Explaining the Simplified Polynomial Function

The function fx x^-2 is a polynomial function with a negative exponent. In this form, it can be rewritten as:

fx 1/x^2

This indicates that the function takes the form of a rational function where the output is the reciprocal of the square of the input (x).

Applications and Graphical Representation

Understanding polynomial functions, including transformations and simplifications, is crucial in various fields such as physics, engineering, and economics. Here are a few applications:

Physics

In physics, understanding the behavior of functions like 1/x^2 can be crucial in calculating gravitational forces, electrostatic forces, or wave propagation in certain media.

Engineering

Engineers use polynomial functions, including those with negative exponents, in the analysis of structural stability, electrical circuit designs, and fluid dynamics.

Economics

In economics, polynomial functions can model supply and demand curves, where the effect of the price change on the demand or supply can be inversely proportional to the square of the change.

Graphical Analysis and Visualization

The graph of the function fx x^-2 is a hyperbola in the first and third quadrants. Here are some key features:

Key Features of the Graph

No x-intercepts: The function never crosses the x-axis because there is no value of x for which 1/x^2 is zero. No y-intercepts: The function passes through the y-axis at (0, undefined) because the function is not defined at x 0. Asymptotes: The function has vertical and horizontal asymptotes. The vertical asymptote is at x 0, and the horizontal asymptote is at y 0.

Conclusion

In conclusion, the polynomial expression fx x^1 x^-1 x^-2 simplifies to fx x^-2, which can be written as fx 1/x^2. This simplification is crucial for understanding the behavior of the function, its applications in various fields, and its graphical representation. By understanding these mathematical concepts, one can better analyze and solve complex problems in science and engineering.
