In mathematics, the absolute value or modulus of a real number x, denoted |x|, is the non-negative value of x without regard to its sign. ... For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.

The absolute value is used in the real world to define the DIFFERENCE or change from one point to another. A good example I found was that if the everybody is going 55 mph and you are going 70 or 40 mph you will most likely get a ticket. It matters because the difference between you and everybody else is 15 mph.

There are two different ways to compare two objects: • The absolute difference is the actual difference between the compared value and the reference value: absolute difference = compared value − reference value. ... The relative difference formula gives a fraction.

The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value.

Absolute value, Measure of the magnitude of a real number, complex number, or vector. Geometrically, the absolute value represents (absolute) displacement from the origin (or zero) and is therefore always nonnegative. ... A complex number z is typically represented by an ordered pair (a, b) in the complex plane.

The absolute value of a Decimal is its numeric value without its sign. For example, the absolute value of both 1.2 and -1.2 is 1.2.

Relative value is a method of determining an asset's worth that takes into account the value of similar assets. This is in contrast with absolute value, which looks only at an asset's intrinsic value and does not compare it to other assets.

For absolute value equations multiplied by a constant (for example,y=a| x |),if 0<a<1, then the graph is compressed, and if a>1, it is stretched. Also, if a is negative, then the graph opens downward, instead of upwards as usual. More generally, the form of the equation for an absolute value function is y=a| x−h |+k.

The absolute value symbol is really shorthand for what we call a piecewise described function. The algebraic definition of abolute value is as follows: |a| = a , if a > 0. - a, if a < 0. That is, the absolute value of a number, a, is equal to the distance that 'a' is from zero.

Algebraically, the absolute value of a number equals the nonnegative square root of its square. The absolute value of a number n, written |n|, can be described geometrically as the distance of n from 0 on the number line. For instance, |42| = 42 and |–42| = 42.

Absolute Value Function Family If x = 0, then y = |0| = 0. If x is positive, then the function value is equal to x. ... Every absolute value graph will take this shape, as long as the expression inside the absolute value is linear.

The absolute value of a number n is written as |n|. The absolute value of 0 is 0. Two numbers are opposites if they have the same absolute value but different signs. Opposites are the same distance from 0 on a number line, and they are on opposite sides of 0.

An absolute value function is a function that contains an algebraic expression within absolute value symbols. Recall that the absolute value of a number is its distance from 0 on the number line. The absolute value parent function, written as f(x)=| x |, is defined as. f(x)={x if x>00 if x=0−x if x<0.

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative. You can write an absolute value inequality as a compound inequality. This holds true for all absolute value inequalities. You can replace > above with ≥ and < with ≤.
