To determine the transformation represented by the graphs, we need to analyze the nature of the plotted points and their locations related to their parent functions.

  • Vertical Compression occurs when the points of a graph are closer to the x-axis compared to the parent function. This is indicated by a factor \( k < 1 \).
  • Vertical Stretch occurs when the points of a graph are further away from the x-axis compared to the parent function. This is indicated by a factor \( k > 1 \).

Given that both sets of graphs represent transformations from their respective parent functions, we can infer from the behavior of the points:

  1. If both graphs are displaced vertically compared to their parent functions but follow a similar pattern (example: straight-line, parabolic), but stay within a certain range without extending too far upwards or downwards, this demonstrates a vertical compression.

  2. If points are further away from the horizontal center (the x-axis) compared to their parent function's placement, then it suggests a vertical stretch.

Since the question states that both graphs represent vertical compressions and since they can have different factors of \( k \), we can conclude that the most fitting response is:

Both graphs represent vertical compressions, although they use different factors of k.
