Answer 1

To determine how the graph of \( f(x) \) transforms to match the graph labeled as Option 3, we need to analyze the transformations of sinusoidal functions.

Key Transformations:

1. Reflection:

   • \( -f(x) \): Reflects across the x-axis.
   • \( f(-x) \): Reflects across the y-axis.

2. Vertical Shift:

   • \( f(x) + k \): Shifts the graph up by \( k \).

3. Horizontal Shift:

   • \( f(x - h) \): Shifts the graph to the right by \( h \).

Analyzing Options:

Since you have multiple options related to transformations of \( f(x) \), we’ll see which can describe Option 3 correctly:

• Option 1: \( -f(x) \)
  This describes a reflection over the x-axis.

• Option 2: \( f(-x) \)
  This describes a reflection over the y-axis.

• Option 3: \( -f(-x) \)
  This is a reflection over both axes (first across the y-axis and then the x-axis).

Conclusion:

Without the actual visual representation, if Option 3 appears to be a reflection of the original graph across both axes, then the correct response would be:

Option 3 is the graph of \( -f(-x) \).

If that's not the case, and you know what the transformation looks like, please share that info for a more accurate response!
