To determine where a function is positive, you need to analyze the function itself. Since you didn’t provide a specific function, I’ll guide you through the general process:
1. Identify Critical Points: Find where the function is equal to zero or undefined to determine intervals to test for positivity.
2. Test Intervals: Choose test points from the intervals created by the critical points and substitute them back into the function to check if the output is positive or negative.
For example, if you have a polynomial function, typically you’d set the function equal to zero and solve for x to find the critical points, then evaluate the function in intervals defined by those points.
Without a specific function, I can’t pinpoint the correct option. However, based on the answer choices you provided, here’s a quick insight:
– If a function is positive in certain intervals, those would be factors in determining the answer.
– “All Real Numbers” would imply the function does not cross the x-axis at all (always positive).
If you can provide more details about the function, I’d be happy to help analyze it further! But based on the options and without specifics provided, I encourage you to determine the intervals where the function is checked for positivity. Let me know if you’d like assistance with a more specific aspect!
