Math Problem Statement
For the function π(π₯) graphed below, solve the inequality π(π₯) > 0 and answer in interval notation:
Solution
To solve the inequality using the given graph, we need to identify the intervals where the function's output is positive, meaning the graph is above the x-axis.
Based on the points plotted on the graph:
- The point indicates , which is positive.
- The point indicates , which is positive.
- The point indicates , which is positive.
- The point indicates , which is positive.
The other points indicate values where .
Now, we determine the intervals:
- From the points, we see that the function is above the x-axis from to and from to .
Therefore, the solution to the inequality is:

Here are five related questions you might consider:
- How can you determine if a function is positive using its graph?
- What does it mean when a function is below the x-axis?
- How would you solve the inequality for the same function?
- What does the point tell you about the function's value at ?
- How can you find where using the graph?
Tip: When working with inequalities involving functions, always pay attention to the intervals where the function changes sign, as these are crucial for determining where the function is positive or negative.
