The graph of f(x) = sin(x) is stretched until it has a period of 4π. this new graph is described by which of the following functions?

a. f(x) = sin(1/4x)
b. f(x) = sin(1/2x)
c. f(x) = sin(2x)
d. f(x) = sin(4x)

First, you need to remember the rules of transformations.

Now, you calculate the stretch factor, based on the period’s growth. (4pi/x=y where x = unstretched period of sin(x), and y = stretch factor.)

The image explains where to go from there.

The answer is idk yo
