Math Problem Statement
Sketch a graph of f(x) = {1 if x <= -1, -2x - 1 if -1 < x <= 2, -3 if x > 2}
Solution
Here is the graph of the piecewise function based on the provided conditions. The graph shows the three segments of the function:
- A horizontal line at for .
- A line segment from to .
- A horizontal line at for .
Please let me know if you need any more details or have any questions.
Follow-up Questions:
- What are the values of at the boundary points and ?
- How would the graph change if the condition changed to ?
- What is the domain and range of the given piecewise function?
- How can we find the slope of the line segment for ?
- What is the significance of open and closed dots in a graph of a piecewise function?
Tip:
When graphing piecewise functions, always carefully check the domain of each piece and use open or closed dots to denote whether a point is included in the segment.
