Option a
Step-by-step explanation:
If the graph of the function represents the transformations made to the graph of then, by definition:
If then the graph is compressed vertically by a factor c.
If then the graph is stretched vertically by a factor c
If then the graph is reflected on the x axis.
If the graph is stretched horizontally by a factor
If the graph is compressed horizontally by a factor
In this problem we have the function and our parent function is
therefore it is true that so and
Therefore the graph of is stretched vertically by a factor c = 4
The answer is "Vertical stretched by a factor of 4"
