Algebra 3-4 Unit 1 Absolute Value Functions and Equations

1: isolate the absolute value expression on one side of the equation with a constant on the other side; 2: set the expression that's inside the absolute value signs equal to both the positive and the negative values of the constant, creating two linear equations; 3: solve each equation, which typically yields two solutions; they can be separated with the word or (this type of solution is ...

The ideal length of a particular metal rod is 35.5 cm. The measured length may vary from the ideal length by at most 0.035 cm. What is the range of acceptable lengths for the rod? 35.465 <= x <= 35.535. Which of the following is the solution to 4 |x + 3| >= 8. x <= -5 or x >= -1. Which of the following is the solution to |x + 11| < 17.

compound inequalities: a pair of inequalities joined by "and" or "or". To solve a compound inequality joined with "and", find the values of the variable that satisfy both inequalities. < 3. The solution is written {x/ -1 < x < 3} (set notation) "all numbers x, such that -1 is less than x is less than 3".

2.6: Absolute Value Inequalities. Determine whether an absolute value inequality corresponds to a union or an intersection of inequalities. Solve absolute value inequalities and express the solutions graphically and in interval notation. Recognize when an absolute value inequality has no solution or all real numbers as the solution.

First, get the absolute value all by itself on the left (remember to reverse the inequality sign when multiplying or dividing by a negative number). Now, separate the equations. We get the first equation by just taking away the absolute value sign away on the left. The easiest way to get the second equation is to take the absolute value sign ...

Figure 19.3.1 19.3. 1: The numbers 5 and −5 − 5 are both five units away from zero. For the equation |x|=5,|x|=5, we are looking for all numbers that make this a true statement. We are looking for the numbers whose distance from zero is 5. We just saw that both 5 and −5−5 are five units from zero on the number line.

1.4.1 Graphs of Absolute Value Functions. In Section 1.3.1, we revisited lines in a function context. In this section, we revisit the absolute value in a similar manner, so it may be useful to refresh yourself with the basics in Section 0.5.2. Recall that the absolute value of a real number , denoted , can be defined as the distance from to on ...
