Question

Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
(x) = cos x/3 ; g(x) = cos x

Answer 1

ok :P

Answer 2

Horizontal stretch by a factor of 3

Vertical stretch by a factor of 3

Vertical shrink by a factor of one third

Horizontal shrink by a factor of one third

Answer 3

I think its vertical stretch by 3?

Answer 5

1 sec :P = )

Answer 6

Horizontal stretch by a factor of 3.

Because the x/3 is in the bracket the stretch will concern the x-axis, and as any transformation in the x-axis does the opposite of what is expected, diving (x/3) would stretch the graph. If it was f(x)=cos(3x) the graph would shrink in the x-axis.
