To determine which option represents the graph of \(-f(x)\), we need to understand that the graph of \(-f(x)\) is the reflection of the graph of \(f(x)\) across the x-axis. This means that all the positive values of \(f(x)\) will become negative, and all the negative values will become positive.
If you have access to the original graph of \(f(x)\) and the different options, you would look for the option where:
- The peaks of \(f(x)\) (maximum points) are inverted to become valleys (minimum points) in \(-f(x)\).
- The troughs of \(f(x)\) (minimum points) are inverted to become peaks in \(-f(x)\).
- The x-intercepts remain the same, as they intersect the x-axis.
Once you identify which option reflects this transformation, that would be the correct answer.
Since I cannot see the actual graph or options, I recommend applying this reasoning to the images you have at hand.
