Explain why the restriction n # - 1 is necessary in the rule x" dx = = xn+1 + C. n + 1 Choose the correct answer below. O A. The restriction is necessary since x "has a vertical asymptote at x = 0. O B. If the restriction was not there, then x - 'dx = ~ + C which is not possible. O C. If the restriction was not there, then x -'dx = x0 + C =1 + C but the derivative of 1 + C is not x O D. The restriction is necessary since x - 'dx = - 5x -2 + C, so the rule shown does not work
