Math Problem Statement

Use the graph to solve –|x – 2| + 4 ≤ 0.

In the xy plane the range of the both axes is negative 8 to 8 by increment of two. The curve is two lines starting from the point (2,4). The first line is passing through the point (6,0). The second line is passing through the point (-8,-6).

x ≤

x ≥

Solution

Given the problem x2+40-|x - 2| + 4 \leq 0, the goal is to find the values of xx that satisfy this inequality.

The graph is described as two lines starting from the point (2,4)(2, 4). This indicates that the graph corresponds to the function y=x2+4y = -|x - 2| + 4. Let's break down the graph and inequality-solving process:

Step 1: Interpretation of the Graph

  • The absolute value function is x2|x - 2|, which creates two linear pieces starting at the vertex (2,4)(2, 4).
  • One line passes through (6,0)(6, 0), implying that for x2x \geq 2, the slope is negative.
  • Another line passes through (8,6)(-8, -6), implying that for x<2x < 2, the slope is positive.

Step 2: Solve the Inequality

We need to solve the inequality x2+40-|x - 2| + 4 \leq 0.

First, rewrite the inequality:

x24-|x - 2| \leq -4 x24|x - 2| \geq 4

This means that the distance between xx and 2 must be at least 4. Therefore, we have two cases:

  1. x24x - 2 \geq 4 which simplifies to x6x \geq 6.
  2. (x2)4-(x - 2) \geq 4 which simplifies to x2x \leq -2.

Final Answer:

  • x6x \geq 6
  • x2x \leq -2

Conclusion:

The solution to x2+40-|x - 2| + 4 \leq 0 is x6x \geq 6 or x2x \leq -2.

Would you like more details on any part of this? Here are 5 related questions:

  1. How do we derive inequalities from absolute value equations?
  2. Can you explain how the graph of x2|x - 2| is constructed?
  3. What does the solution set x6x \geq 6 or x2x \leq -2 look like on a number line?
  4. How does shifting and flipping affect the graph of absolute value functions?
  5. How would the inequality change if we replaced 0 with a positive number in x2+4c-|x - 2| + 4 \leq c?

Tip: When solving absolute value inequalities, always consider both cases (positive and negative) for the expression inside the absolute value.
