What is Absolute Value Function? An absolute value function is a function in algebra where the variable is inside the absolute value bars. This function is also known as the modulus function and the most …

Jul 23, 2025 · An absolute value function is a function that takes the absolute value of the input. The absolute value of a number is its distance from zero on the number line, regardless of direction, …

This is the Absolute Value Function: f (x) = x. It is also sometimes written: abs (x). This is its graph: f (x) = x.

The absolute value function is commonly thought of as providing the distance the number is from zero on a number line. Algebraically, for whatever the input value is, the output is the value without regard …

Dec 4, 2025 · The absolute value function assigns to each real number its distance from zero on the number line. This means that negative numbers are mapped to their positive counterparts, while …

The absolute value function is explored through definitions, examples and exercises with solutions at the bottom of the page. The graphing of absolute value functions |f (x)| is discussed through examples.

When computing absolute values, we find [latex]|0| = 0 [/latex], [latex]|\pi| = \pi [/latex] and [latex]|117.42| = 117.42 [/latex]. In general, if [latex]x \geq 0 [/latex], the absolute value function does nothing to …

In this explainer, we will learn how to evaluate and graph absolute value functions and identify their domain and range. Recall that the absolute value of a real number is its distance from 0 on the …

In this section, we will investigate absolute value functions. Recall that in its basic form f (x) = ∣ x ∣ f (x)=∣x∣, the absolute value function, is one of our toolkit functions. The absolute value function is …

Jan 2, 2021 · The absolute value function is commonly thought of as providing the distance the number is from zero on a number line. Algebraically, for whatever the input value is, the output is the value …
