*6. A function y = f(x) exists such that lim f(x) - 9, lim f(x) - 7, and f(-4) = 7 As each statement is true or false? If the statement is false, explain why. a) y = f(x) is continuous at x = -4. b) The limit of f(x) as x approaches -4 does not exist. c) When x = -4, the value of the function is 9. d) The right-hand limit and the value of the function are equal. e) When x =-4, the value of the function is 7. f) The function is discontinuous at X
