Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
(x) = cos x divided by three; g(x) = cos x

Horizontal stretch by a factor of 3

Step-by-step explanation:

Given:

Function transformation rule used:

When is multiplied by a constant then the function is either stretched or compressed in horizontal direction.

If the then its a horizontal compress.

If the then its a horizontal stretch.

Function transformation taking place:

The constant term multiplied in the above transformation comes to be which is , which means that the transformation would be a horizontal stretch by a factor of 3.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

the answer is 21%.
