Vector Output at Specific Point

Given a function with two-dimensional input $(x, y)$ and a vector output, determine the vector at a specific input point such as $(1, 2)$ using the functions $(y^3 - 9y)$ for the x-component and $(x^3 - 9x)$ for the y-component.

In this problem, you will explore the evaluation of a vector-valued function at a specific point in its domain. The key idea here is understanding how functions with vector outputs work and how to calculate and interpret their components individually. Given a two-dimensional input, the function produces a vector with distinct expressions for each component, offering insight into how variables interact within these expressions. A strategic approach involves evaluating each component of the vector independently by substituting the given input values into their respective functions. This allows you to manage the problem in a structured manner, reducing potential complexities from dealing with multiple variables simultaneously. Conceptually, problems like these often require knowledge of substitution techniques and a basic understanding of multivariable function inputs. They highlight the beauty of vector functions in translating movement or change in one dimension into potentially different effects in another, a foundational concept in fields like physics and engineering. While calculating, it's important to maintain clarity in your steps, systematically working through each component. Understanding the nature of this function evaluation will deepen your appreciation for the mathematical depiction of complex systems through vector functions, ultimately enriching your computational fluency in multivariable calculus.
