A squaring function is a type of mathematical function that takes a number as an input, squares it (i.e., raises it to the power of 2), and produces the result as the output. The general form of a squaring function is:

f(x) = x^2

Here, “f(x)” represents the output or the value of the function at a given input x. The “^” symbol denotes exponentiation. In this case, x is the input, and x^2 represents x squared.

To understand the behavior of a squaring function, let’s consider a few key points:

1. The domain: The domain of a squaring function is all real numbers since any real number can be squared.

2. The range: The range of a squaring function is all non-negative real numbers (including zero). In other words, the outputs of a squaring function can only be positive or zero, but not negative.

3. Symmetry: The graph of a squaring function is symmetric about the y-axis. This means that if you have a point (x, y) on the graph, then (-x, y) will also be on the graph.

4. Translations: You can shift the graph of a squaring function horizontally or vertically by adding or subtracting constants. For example, the function g(x) = (x – 3)^2 would shift the graph of f(x) = x^2 three units to the right, while the function h(x) = x^2 + 2 would shift the graph two units up.

5. Increasing or decreasing: The squaring function is always increasing for positive values of x. This means that as x increases, the corresponding y-values also increase. However, for negative values of x, the squaring function is decreasing. As x becomes more negative, the y-values become more positive.

When graphed, a squaring function will form a curve known as a parabola. The vertex of the parabola is located at the point (0, 0), which is the origin. The parabola opens upwards, indicating that the function is always positive or zero.

In summary, a squaring function is a mathematical function that takes an input, squares it, and produces the result as the output. It has a range of all non-negative real numbers, and its graph is a symmetric parabolic curve that opens upwards.
