If f(x) = 81x² + 18x + 1 a) Use direct substitution to find lim f(x). x--1 b) Is f(x) a continuous function at x = -1? c) If this is a continuous function at x -1, what are all the criteria that it meets? If it is not, write down a condition that it fails to meet and name the discon- tinuity. = If f(x) = 81x² + 18x + 1 a) Use direct substitution to find lim f(x). x--1 b) Is f(x) a continuous function at x = -1? c) If this is a continuous function at x -1, what are all the criteria that it meets?
