Answer:
The graph of
is a vertical stretch of 5 units and a horizontal stretch by 2 units of the parent graph
Explanation:
We want to find out how the graph of
compare with the graph of the parent function
.
We can observe that the transformation applied to the basic cosine function is of the form:

The
is a vertical stretch by a factor of 5 units.
is a horizontal stretch by a factor of 2 units.
Therefore the graph of
will stretch vertically by a factor of 5 units and stretch horizontally by a factor of 2 units as compared to
.
