Which single transformation can be applied to the graph of y = 72 to produce the graph of y = 9 ? A. vertical translation
xxB. vertical compression
C. horizontal translation
D. horizontal compression
its b

B. Vertical Compression

Step-by-step explanation:

You've answered the question; However, I'll assist with the explanation;

Given

Original:

Translated:

Required

Determine the type of transformation applied to the original function

Observing both functions, we notice that is a common factor;

This implies that the function was compressed or stretched along the y axis (vertically)

To determine if its vertical compression or stretch;

We have to divide the translated function by the original function;

Because 0.125 < 1, then the transformation is a vertical compression

answer: x=60
