Math Problem Statement
Solution
The problem displayed asks: "Find all values of for which " based on the graph of the function shown.
Analysis:
From the graph, you need to determine where the function is greater than zero (i.e., where the graph is above the x-axis). Here's how to analyze it:
-
Identify the x-intercepts: The points where the graph crosses the x-axis are the values of where .
-
Determine intervals where : Look for sections of the graph that lie above the x-axis. These will be the intervals of for which .
Based on the graph in the image:
- The function appears to cross the x-axis at two points. Let’s approximate these points.
- The graph crosses the x-axis at around and .
Conclusion:
- The function is positive (i.e., ) for the interval between the two x-intercepts, meaning for .
Thus, the solution is:
Would you like further details or have any questions? Here are some related questions you might find useful:
- How do we calculate x-intercepts algebraically?
- What is the difference between and ?
- How would this change if the function were shifted vertically?
- What happens if the function dips below the x-axis for a larger interval?
- How do you determine concavity from the graph?
Tip: Always check the points where the function crosses the x-axis carefully, as they help you determine when a function is positive or negative.
