Answer: OPTION B.
Step-by-step explanation:
Below are some transformations for a function f(x):
1. If and
, the function is compressed horizontally by a factor of
.
2. If and
, the function is stretched horizontally by a factor of
.
3. If and
, the function is compressed vertically by a factor of "b".
4. If and
, the function is stretched vertically by a factor of "b".
In this case you have the function f(x):
And the function g(x):
So, you can identify that:
and
Therefore, the graph of the function g(x) is a vertical compression of the graph of function f(x).
