Solution
To express the graph as a piecewise function, let's analyze each segment of the graph:
-
First Segment:
- This segment starts at the point (-6, -8) and ends at (2, 4).
- We can find the equation of the line by determining the slope () and using the point-slope form.
Slope Calculation:
Using the point-slope form with the point (-6, -8): Simplifying, we get:
This segment is valid for (it’s open at because there’s an open circle at that point).
So, the function for this segment is:
-
Second Segment:
- This segment starts at and ends at , with the points (2, 5) and (6, 7).
- Since this segment is linear, we can calculate the slope and find its equation similarly.
Slope Calculation:
Using the point-slope form with the point (2, 5): Simplifying, we get:
This segment is valid for (open at and closed at ).
So, the function for this segment is:
Final Piecewise Function:
Combining these two segments, the piecewise function is:
\frac{3}{2}x + 1 & \text{for } -6 \leq x < 2 \\ \frac{1}{2}x + 4 & \text{for } 2 < x \leq 6 \end{cases}$$ Would you like further clarification on any part of this solution? Here are some related questions that might deepen your understanding: 1. How would the piecewise function change if the endpoints were different? 2. What if the graph had more than two segments—how would that affect the piecewise function? 3. Why is it important to pay attention to open and closed intervals in piecewise functions? 4. How can you check that the equations for each segment are accurate representations of the graph? 5. What happens if two segments in a piecewise function meet at a discontinuous point? **Tip:** Always confirm the slope and intercepts of each segment separately to avoid errors when creating piecewise functions from graphs.Ask a new question for Free
