The expression (h(x))^2 represents the square of a function h(x). This means that you take the output of the function h for a given input x and multiply it by itself. For example, if h(x) = 3, then (h(x))^2 = 3^2 = 9. Squaring a function can change its shape and properties, often making it non-negative. In mathematics, squaring a function is a common operation used in various fields, including algebra and calculus. It can help in analyzing the behavior of functions, such as finding maximum or minimum values. Additionally, squaring is essential in geometry for calculating areas and in physics for equations involving energy and motion.
