x+2 Exercise 2 [17 points]. All the problems involve the function f (x) = x2 - 2.x - 8 (a) [02 points]. Find lim f (x) = I-+00 (b) [03 points]. Find lim f(x) = (c) [02 points each]. Find the vertical and horizontal asymptotes of f(). (d) [02 points each]. Find the x-values at which f(x) is not continuous (ex- plain). (e) [04 points]. If there is any removable discontinuity for f (x), then remove it by defining a new function f(x)
