Absolute Value Introduction The absolute value of a number is its value, or magnitude, without respect to sign.

An absolute value is written like this: This is now a finite value and so this series will also be convergent. In the interval - inf2 the graph of f is a parabola shifted up 1 unit. If you need a refresher you should go back and review that section.

However, this does provide us with a nice example of how to use the idea of stripping out terms to our advantage. Maybe it's a crude approximation, but it makes for an easy calculation of area. Using the absolute value guarantees we have a positive value inside the bars, so the negative sign will definitely make it negative.

As you move the pink points, a rectangle is highlighted, and the calculation of its area is shown in the upper right corner. In both cases the magnitude, or absolute value, of your number is just plain old "9" because you've removed any negative sign that might have existed.

The graphs section contains commands for plotting equations and inequalities. Graphs of Absolute Value Functions Note that you can put absolute values in your Graphing Calculator and even graph them.

It can be said that function f is piecewise constant. An absolute value is written like this: In certain places, such as calculator and computer programs, you may see it written as abs xwhich naturally means "the absolute value of x," but x is the common way your teacher probably wants you to write it on your homework and tests.

The inequalities section lets you solve an inequality or a system of inequalities for a single variable. Solutions and Solution Sets We will start off this chapter with a fairly short section with some basic terminology that we use on a fairly regular basis in solving equations and inequalities.

Area via a left Riemann sum. Suppose that a coordinate grid is placed over a putt-putt golf course, where Amy is playing golf. What is the integral adding up. However, notice that both parts of the series term are numbers raised to a power.

Now, there is no reason to think that a given equation or inequality will only have a single solution. In this case our answer is all real numbers, since an absolute value is always positive.

It is a nice notation and does have some use on occasion especially for complicated solutions. Example 1 Show that each of the following numbers are solutions to the given equation or inequality. Applications Another use of the absolute value bars is actually to force a number to be negative, by writing - x.

We first have to get the absolute value all by itself on the left. You can also type in more problems, or click on the 3 dots in the upper right hand corner to drill down for example problems.

Applications of Absolute Value Functions Absolute Value Functions are in many applications, especially in those involving V-shaped paths and margin of errors, or tolerances. It will be fairly easy to get this into the correct form.

It's the "amount" you are working with expressed as a positive number, ignoring any negative sign. Try the answers in the original equation to make sure they work. Therefore, if we start out with 1.

(Note that with non-linear equations, there will most likely be more than one intersection; an example of how to get more than one solution via the Graphing Calculator can be found in the Exponents and Radicals in Algebra section.) Solving Systems with Substitution.

Purplemath. Exponents are shorthand for repeated multiplication of the same thing by itself. For instance, the shorthand for multiplying three copies of the number 5 is shown on the right-hand side of the "equals" sign in (5)(5)(5) = 5 elleandrblog.com "exponent", being 3 in this example, stands for however many times the value is being multiplied.

The thing that's being multiplied, being 5 in this. Negative rate of change When the value of x increases, the value of y decreases and the graph slants downward.

Zero rate of change When the value of x increases, the value of y remains constant. That is, there is no change in y value and the graph is a horizontal line.
