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 , the goal is to find the values of that satisfy this inequality.
The graph is described as two lines starting from the point . This indicates that the graph corresponds to the function . Let's break down the graph and inequality-solving process:
Step 1: Interpretation of the Graph
- The absolute value function is , which creates two linear pieces starting at the vertex .
- One line passes through , implying that for , the slope is negative.
- Another line passes through , implying that for , the slope is positive.
Step 2: Solve the Inequality
We need to solve the inequality .
First, rewrite the inequality:
This means that the distance between and 2 must be at least 4. Therefore, we have two cases:
- which simplifies to .
- which simplifies to .
Final Answer:
Conclusion:
The solution to is or .
