(1 point) The following three functions look very similar, but define very different functions. Think about how they are defined and write each as a composition of functions given the information below. (None of the functions in your compositions should be the same as the given function.) 1. cos (x) = f(g(x)) where f(x) = . and g(x) = 2. cos(cos(x)) = f(e(x)) where f(x) = , and g(x) = 3. cos = f(g(x)) where f(x) = and g(x) =
