How to write absolute value equations as piecewise equations and inequalities

A bird is approaching Erin, a photographer, and she films it. We first have to get the absolute value all by itself on the left.

Piecewise Functions

The first theorem required a linear differential equation. That costs more than a human haircut at least my haircuts! Piecewise Function Word Problems Problem: This is commonly referred to as taking the logarithm of both sides. Try it; it works! Graphing Absolute Value Functions Example.

I like to then make the expression on the right hand side without the variables both positive and negative and split the equation that way. This means we can write this absolute value function as a piecewise function. Welcome to She Loves Math!

You plan to sell She Love Math t-shirts as a fundraiser. And, even better, a site that covers math topics from before kindergarten through high school.

Piecewise Functions

So, just what does this theorem tell us? Here are more problems: Learn these rules, and practice, practice, practice! You might want to review Quadratic Inequalities for the second example below: We have to start at 0, since dogs have to weigh over 0 pounds: First let's take a look at a theorem about linear first order differential equations.

Even with the absolute value, we can set each factor to 0, so we get —4 and 1 as critical values. Write a function that models this situation. Here are some examples: Check the answers; the work! That is because we want to use the following property with this one.

Unlike the first theorem, this one cannot really be used to find an interval of validity. Write a function that models this situation. How high the did the ball bounce for the second student to catch it? So we will need to divide out by the coefficient of the derivative.

The purpose of this work is for students to think about the meaning of absolute value and how the absolute value function appears on a graph. Obtaining Equations from Piecewise Function Graphs You may be asked to write a piecewise function, given a graph. You might want to review Solving Absolute Value Equations and Inequalities before continuing on to this topic.

Note that we get some complex roots since we had to take the square root of a negative number. Put in numbers and try it! How high the did the ball bounce for the second student to catch it? 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.This book provides a quick introduction to Pyomo, which includes a collection of Python software packages that supports a diverse set of optimization capabilities for formulating and analyzing optimization models.

In this section we will give an in depth look at intervals of validity as well as an answer to the existence and uniqueness question for first order differential equations. Used and loved by over 6 million people Learn from a vibrant community of students and enthusiasts, including olympiad champions, researchers, and professionals.

Obtaining Equations from Piecewise Function Graphs. You may be asked to write a piecewise function, given a graph.

Now that we know what piecewise functions are all about, it’s not that bad! Functions and equations Here is a list of all of the skills that cover functions and equations! These skills are organized by grade, and you can move your mouse over any skill name to preview the skill.

N Number and Quantity. N-RN The Real Number System. Extend the properties of exponents to rational exponents. N-RN.1 Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents.
