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.

The absolute value function of a real number returns its value irrespective of its sign, whereas the sign (or signum) function returns a number's sign irrespective of its value. The following equations show the relationship between these two functions:
2 sty 2021 · Learn how to graph, write, and solve absolute value functions, which are toolkit functions that provide the distance of a number from zero. See examples, exercises, and applications of absolute value functions in math and science.
Learn the definition, graph, domain, range and algebra of the absolute value function. It is a piecewise function that makes a right angle at (0,0) and is an even function.
19 lut 2024 · 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.
The absolute value function can be defined as a piecewise function. f(x) = |x| = {x if x ≥ 0 − x if x <0. Example 1. Using Absolute Value to Determine Resistance. Electrical parts, such as resistors and capacitors, come with specified values of their operating parameters: resistance, capacitance, etc.
Learn how to graph and solve absolute value functions, which are toolkit functions that provide the distance a number is from zero on a number line. See examples, exercises, and applications of absolute value functions in real-world problems.
