Math Problem Statement

Given a graph representing a piecewise function f(x), identify the conditions for which f(x) takes the values 5, -1, and 3.

Solution

From the image you uploaded, the graph appears to represent a piecewise function f(x)f(x) where the value of the function changes depending on the value of xx. The goal is to fill in the conditions for each value of f(x)f(x).

Analyzing the Graph

  • For f(x)=5f(x) = 5:

    • There is a horizontal line at y=5y = 5 from x=6x = -6 to x=2x = -2. This means f(x)=5f(x) = 5 when 6x2-6 \leq x \leq -2.
  • For f(x)=1f(x) = -1:

    • There is another horizontal line at y=1y = -1 between x=0x = 0 and x=2x = 2, but excluding x=0x = 0 (open circle at x=0x = 0) and including x=2x = 2 (closed circle at x=2x = 2). This means f(x)=1f(x) = -1 when 0<x20 < x \leq 2.
  • For f(x)=3f(x) = 3:

    • There is a single point at (4,3)(4, 3), which means f(x)=3f(x) = 3 when x=4x = 4.

Solution:

The piecewise function f(x)f(x) can be written as:

5 & \text{if } -6 \leq x \leq -2 \\ -1 & \text{if } 0 < x \leq 2 \\ 3 & \text{if } x = 4 \end{cases}$$ Let me know if you'd like more details or explanations! --- Here are 5 related questions for practice: 1. What would $$f(x)$$ be if $$x = -3$$? 2. Is $$f(x)$$ defined at $$x = 0$$? Why or why not? 3. Can you graph the intervals where $$f(x) = 0$$? 4. How would the graph change if the point at $$x = 4$$ were at $$(4, 5)$$? 5. What happens if the condition $$f(x) = 3$$ is extended to an interval, say $$3 \leq x \leq 5$$? **Tip:** Always check for open and closed circles on graphs to see whether a value is included or excluded at a specific point.
