Question 1067214: The function y=(1/5)2^x.Which statement accurately
compares the graph below with the graph of y=2^x?
A. The graph above is a vertical compression of the graph of y=2^x
B. The graph above is a vertical stretch of the graph of y=2^x
C. The graph above is a vertical translation of the graph of y=2^x
D. The graph above is a horizontal translation of the graph of y=2^x

We are given the function
:
y = 2^x
:
Note that y = C * (2^x) is the form we want to consider when C is a constant
:
We are given C = (1/5)
:
C > 1 stretches it
0 < C < 1 compresses it
:
0 < (1/5) < 1
:
Answer is A
:
We can see this from the graph, red line is 2^x and green line is (1/5)2^x
:
