Question: What is the significance of the x-intercepts of a function?

Options:

1. They indicate the maximum value of the function.
2. They indicate the minimum value of the function.
3. They are the points where the function crosses the x-axis.
4. They are the points where the function is undefined.

Correct Answer: They are the points where the function crosses the x-axis.

Solution:

The x-intercepts of a function are the points where the graph crosses the x-axis, meaning the output of the function is zero at those points.
