Math Problem Statement
For f(x) = |x| + 2, then f(-2) = 0. True or False?
Solution
Let's analyze the question.
The given function is:
You are tasked with determining whether is true or false.
Step 1: Evaluate
Substitute into the function:
The absolute value of is . So:
Step 2: Check if
Clearly, , which is not equal to 0.
Conclusion:
The statement is false.
Let me know if you'd like a detailed explanation or have any follow-up questions! Here are some related questions to consider:
- What is the range of the function ?
- How does the absolute value function influence the graph of ?
- What are the x-values that make ?
- Can for any real ?
- How would the function change if ?
Tip: When working with absolute value functions, always simplify the absolute value expression before applying further operations!
