Absolute Value Function - Definition, Equation, Examples
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 commonly used form of the absolute value function is f(x) = |x|, where x is a real number.

2021年1月2日 · The absolute value function is commonly used to measure distances between points. Applied problems, such as ranges of possible values, can also be solved using the absolute value function. The graph of the absolute value function resembles a letter V. It has a corner point at which the graph changes direction.

2024年2月19日 · Understanding Absolute Value. Recall that in its basic form f(x) = |x|, the absolute value function is one of our toolkit functions. The absolute value function is commonly thought of as providing the distance the number is from zero on a number line.
Absolute Value Function - Math is Fun
Absolute Value Function. This is the Absolute Value Function: f (x) = |x|. It is also sometimes written: abs (x) This is its graph: f (x) = |x|. It makes a right angle at (0,0) It is an even function. Its Domain is the Real Numbers: Its Range is the Non-Negative Real Numbers: [0, +∞) Are you absolutely positive? Yes! Except when I am zero.

Lesson Explainer: Absolute Value Functions | Nagwa
An absolute value function is a function with a definition that contains an algebraic expression within absolute value symbols. An example of an absolute value function is 𝑔 (𝑥) = | 𝑥 |, where 𝑥 ∈ ℝ.
Absolute Value Functions Examples
We can use this to get a third point as well, using the symmetry of absolute value functions to our advantage. We know (5, 3) is one point to the right of the vertex; if we go one point to the left of the vertex, we'll also have y = 3. So (3, 3) is our third point on the graph. Graphing absolute value functions is elementary, dear Shmooper.
