Math Problem Statement

What is the piecewise function represented by the graph?

Solution

The graph you uploaded shows a piecewise linear function, with points connected by straight segments. Here’s an analysis of the key points and structure of the graph:

  1. Key Points on the Graph:

    • The graph starts with an open circle at (6,2)(-6, 2), indicating that the value at this point is not included in the function.
    • The line moves downward to the point (2,3)(-2, -3).
    • From (2,3)(-2, -3), it moves upward to the point (1,2)(1, 2).
    • Then, it continues upward to (3,6)(3, 6), where there is a closed circle, meaning this point is included in the function.
  2. Slopes of the Line Segments:

    • Between (6,2)(-6, 2) and (2,3)(-2, -3), the slope can be calculated as: m=322(6)=54=54m = \frac{-3 - 2}{-2 - (-6)} = \frac{-5}{4} = -\frac{5}{4}
    • Between (2,3)(-2, -3) and (1,2)(1, 2), the slope is: m=2(3)1(2)=53m = \frac{2 - (-3)}{1 - (-2)} = \frac{5}{3}
    • Between (1,2)(1, 2) and (3,6)(3, 6), the slope is: m=6231=42=2m = \frac{6 - 2}{3 - 1} = \frac{4}{2} = 2
  3. Piecewise Function Representation: The function can be written as a piecewise function with three distinct intervals:

    -\frac{5}{4}(x + 6) + 2 & \text{for } -6 < x \leq -2 \\ \frac{5}{3}(x + 2) - 3 & \text{for } -2 \leq x \leq 1 \\ 2(x - 1) + 2 & \text{for } 1 \leq x \leq 3 \end{cases}$$

Would you like more detailed explanations or clarifications?

Here are 5 related questions:

  1. What does the open circle at (6,2)(-6, 2) signify in the context of the function?
  2. How would the graph look if the circle at (6,2)(-6, 2) were closed?
  3. Can you express this function in interval notation for its domain and range?
  4. How would you find the x-intercepts and y-intercepts of this piecewise function?
  5. How does the slope between points affect the steepness of the line segments?

Tip: In piecewise functions, open and closed circles are important in determining whether a value at that point is included or excluded from the function!
