Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x) = cos x/2 ; g(x) = cos x

We are given

now, we can find relation between f(x) and g(x)

Since, g(x) is parent function

so, we get

Since, there is change in x as x/2

so, x is divide by 2

So, it is horizontal stretch by 2 units..........Answer

ok then what happened.
