Absolute value of -4.

Definition: Absolute Value Function. The absolute value function can be defined as. f(x) = |x| = { x if x ≥ 0 − x if x < 0. The absolute value function is commonly used to determine the distance between two numbers on the number line. Given two values a and b, then |a − b| will give the distance, a positive quantity, between these values ...Answer: 4.5. Step-by-step explanation: absolute value: the distance away from zero, it will always be positive because distance can't be negative. thus, the absolute value of 4.5 = the distance of 4.5 to zero, which is 4.5. |4.5| = 4.5. arrow right.Extreme value theorem tells us that a continuous function must obtain absolute minimum and maximum values on a closed interval. These extreme values are obtained, either on a relative extremum point within the interval, or on the endpoints of the interval. Let's find, for example, the absolute extrema of h ( x) = 2 x 3 + 3 x 2 − 12 x over the ...For example, -4 and 4 both have an absolute value of 4 because they are each 4 units from 0 on a number line—though they are located in opposite directions from 0 on the number line. When solving absolute value equations and inequalities, you have to consider both the behavior of absolute value and the properties of equality and inequality.

The procedure to use the absolute value calculator is as follows: Step 1: Enter the number in the respective input field. Step 2: Now click the button "Solve" to get the result. Step 3: Finally, the absolute value of the given number will be displayed in the output field.A number's absolute value can never be negative. The absolute value of 5 is 5, for example, and the absolute value of 5 is also 5. The absolute value of a number can be conceived of as its position on the real number line in relation to zero. Furthermore, the distance between two real numbers is the absolute value of their difference.

This tutorial shows you how to use a formula to find the absolute value of a complex number. Keywords: problem; absolute value; complex numbers; pythagorean theorem; complex plane;

Absolute value is a way to think about a number's size. Simply put, the absolute value of a number is the distance between the number and zero on the number line. Since absolute value represents a distance, the result will always be non-negative. This means the absolute value of a number can be only 0 or larger.In this case, a = 4 and b = -3, so: |4 - 3i| = √ ( (4)^2 + (-3)^2) = √ (16 + 9) = √25 = 5. So, the absolute value of 4 - 3i is 5. The absolute value of the complex number 4 - 3i, represented as |4-3i|, is equal to 5. This conclusion is reached by applying the formula for absolute value. Option D is answer.

To understand this, how does one work out the absolute value of: A = (1 0 0 −1) A = ( 1 0 0 − 1) Clearly A† = A A † = A so |A| = A2−−−√ | A | = A 2, but this is not necessarily A A. I want to pick the identity in this case, since ...Use this calculator to find the absolute value of any number, including -4. The symbol for absolute value is | x | where | x | = x, and | -x | = x. Learn the definition, formula and examples of absolute value.In algebra, an absolute value (also called a valuation, magnitude, or norm, [1] although "norm" usually refers to a specific kind of absolute value on a field) is a function which measures the "size" of elements in a field or integral domain. More precisely, if D is an integral domain, then an absolute value is any mapping |x| from D to the ...

The real way to look at absolute values is that they are a number's distance from 0 on the number line: TRY IT: Use a number line to show the answers to these. 1. of 1.

Graph an absolute value function. The most significant feature of the absolute value graph is the corner point at which the graph changes direction. This point is shown at the origin. Figure 4 is the graph of \displaystyle y=2\left|x - 3\right|+4 y = 2∣x − 3∣ + 4. The graph of \displaystyle y=|x| y = ∣x∣ has been shifted right 3 units ...

Inside the absolute-value bars of this function, I've got a quadratic. Without the absolute-value bars, the graph of the quadratic inside the bars is a generic parabola. I can confirm (by factoring) that the x-intercepts are at x = −1 and x = 4. I can use a formula to confirm that the vertex is at (1.5, −6.25). The y-intercept is at y = −4.A number's absolute value can never be negative. The absolute value of 5 is 5, for example, and the absolute value of 5 is also 5. The absolute value of a number can be conceived of as its position on the real number line in relation to zero. Furthermore, the distance between two real numbers is the absolute value of their difference.3.5: Absolute Value Functions. There are a few ways to describe what is meant by the absolute value | x | of a real number x. You may have been taught that | x | is the distance from the real number x to 0 on the number line. So, for example, | 5 | = 5 and | − 5 | = 5, since each is 5 units from 0 on the number line.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 to sign. Knowing this, we can use absolute value functions to solve some kinds of real-world problems. The absolute value of a number may be thought of as its distance from zero. In mathematics, the absolute value or modulus of a real number , denoted , is the non-negative value of without regard to its sign. Namely, if is a positive number, and if is negative (in which case negating makes positive), and . For example, the absolute value of 3 is ... This will give you two answers. The first case: Everything was already positive: |x-3/2|> 5 becomes x-3/2>5. So you add 3/2 to both sides and one of the two answers is x>6 1/2. Second case: (x-3/2) was a negative number, whose absolute value was greater than 5. That means that (x-3/2) was a number that was less than negative 5:
