() Consider the functions A. y=x" B. y = x/n C. y=x-n where n is an integer greater than 1 (n = 2, 3,...). Which of these functions increases most steeply for values of a greater than 1? ? Which decreases for large values of x? ? Which of these functions is not defined at x= 0? ? Note: In order to get credit for this problem all answers must be correct.
