Which of the graphs below represents the solution set for $| x - 3 | - 4 = 0$ .

Short Answer

Expert verified

The correct solution is

Step by step solution

Step 1- Apply the concept of absolute value.

Absolute value describes the distance from zero that a number is on the number line,without considering direction. The absolute value of a number is never negative.

Step 2- Simplify the expression.

Consider the expression $| x - 3 | - 4 = 0$ .

Add 4 on both sides of the equation as follows:

$\begin{array}{l} | x 鈭� 3 | 鈭� 4 = 0 \\ | x 鈭� 3 | 鈭� 4 + 4 = 4 \\ | x 鈭� 3 | = 4 \end{array}$

Step 3- Step description.

Apply the absolute rule as follows:

Case 1. When $x - 3 = 4$ .

$\begin{array}{l} x 鈭� 3 = 4 \\ x = 4 + 3 \\ x = 7 \end{array}$

Case 2. When $x - 3 = - 4$

$\begin{array}{l} x 鈭� 3 = 鈭� 4 \\ x = 鈭� 4 + 3 \\ x = 鈭� 1 \end{array}$

Therefore, the value is $x = - 1, 7$ .

Step 4- Step description.

The correct solution is option (B).
